Unfortunately, personal finance is not a required subject in most high schools or colleges. This lack of basic financial education leaves many young adults clueless about how to manage their money, applying for credit, and how to get or stay out of debt.

To help you get started, we'll take a look at eight of the most important things to understand about money. These financial tips for young adults are designed to help you live your best financial life.

#1. Learn Self-Control

If you're lucky, your parents taught you this skill when you were a kid. If not, keep in mind that the sooner you learn the fine art of delaying gratification, the sooner you'll find it easy to keep your finances in order. Although you can effortlessly purchase an item on credit the minute you want it, it's better to wait until you've actually saved up the money. Do you really want to pay interest on a pair of jeans or a box of cereal?

If you make a habit of putting all your purchases on credit cards, regardless of whether you can pay your bill in full at the end of the month, you might still be paying for those items in 10 years.

Key Takeaways Unfortunately, a class called "finance for young adults" isn't usually part of a high school curriculum.

Saving for retirement is an integral part of any financial plan, no matter what your age.

Taking the time to learn a few critical financial rules may help you build a healthy financial future.

Learning to prepare your annual tax return yourself could save you money.

Start an emergency fund and pay into it every month, even if it is a small amount.

If you want to keep your credit cards for the convenience factor or the rewards they offer, make sure to always pay your balance in full when the bill arrives, and don't carry more cards than you can keep track of. This financial tip is crucial for creating a healthy future for your credit history.

#2. Control Your Financial Future

If you don't learn to manage your own money, other people will find ways to (mis)manage it for you. Some of these people may be ill-intentioned, like unscrupulous commission-based financial planners. Others may be well-meaning, but may not know what they're doing, like Grandma Betty who really wants you to buy a house even though you can only afford a treacherous adjustable-rate mortgage.

Instead of relying on others for advice, take charge and read a few basic books on personal finance. Once you're armed with personal finance knowledge, don't let anyone catch you off guard—whether it's a significant other that slowly siphons your bank account or friends who want you to go out and blow tons of money with them every weekend.

#3. Know Where Your Money Goes

Once you've gone through a few personal finance books, you'll realize how important it is to make sure your expenses aren't exceeding your income. The best way to do this is by budgeting.

Once you see how your morning java adds up over the course of a month, you'll realize that making small, manageable changes in your everyday expenses can have just as big of an impact on your financial situation as getting a raise.

In addition, keeping your recurring monthly expenses as low as possible will also save you big bucks over time. If you don't waste your money on a posh apartment now, you might be able to afford a nice condo or a house before you know it.

Understanding how money works is the first step toward making your money work for you.

#4. Start an Emergency Fund

One of personal finance's oft-repeated mantras is "pay yourself first." No matter how much you owe in student loans or credit card debt, and no matter how low your salary may seem, it's wise to find some amount—any amount—of money in your budget to save in an emergency fund every month.

Having money in savings to use for emergencies can really keep you out of trouble financially and help you sleep better at night. Also, if you get into the habit of saving money and treating it as a non-negotiable monthly "expense," pretty soon you'll have more than just emergency money saved up: you'll have retirement money, vacation money, and even money for a down payment on a home.

Don't just sock away this money under your mattress; put it in a high-interest online savings account, a certificate of deposit, or a money market account. Otherwise, inflation will erode the value of your savings.

#5. Start Saving for Retirement

Just as you headed off to kindergarten with your parents' hope to prepare you for success in a world that seemed eons away, you need to prepare for your retirement well in advance. Because of the way compound interest works, the sooner you start saving, the less principal you'll have to invest to end up with the amount you need to retire and the sooner you'll be able to call working an "option" rather than a "necessity."

Company-sponsored retirement plans are a particularly great choice because you get to put in pre-tax dollars, companies will often match part of your contribution, which is like free money, and the contribution limits tend to be high (much more than you can contribute to an individual retirement plan).﻿﻿

#6. Get a Grip on Taxes

It's important to understand how income taxes work even before you get your first paycheck. When a company offers you a starting salary, you need to know how to calculate whether that salary will give you enough money after taxes to meet your financial goals and obligations.

Fortunately, there are plenty of online calculators that have taken the dirty work out of determining your own payroll taxes, such as PaycheckCity.com. These calculators will show you your gross pay, how much goes to taxes and how much you'll be left with, which is also known as net, or take-home pay.

For example, $35,000 a year in New York will leave you with around $27,455 after taxes without exemptions in 2019, or about $2,290 a month.﻿﻿

By the same token, if you're considering leaving one job for another in search of a salary increase, you'll need to understand how your marginal tax rate will affect your raise and that a salary increase from $35,000 a year to $41,000 a year won't give you an extra $6,000, or $500 per month—it will only give you an extra $4,195, or around $350 per month (again, the amount will vary depending on your state of residence).﻿﻿

#7. Guard Your Health

If meeting monthly health insurance premiums seems impossible, what will you do if you have to go to the emergency room, where a single visit for a minor injury like a broken bone can cost thousands of dollars? If you're uninsured, don't wait another day to apply for health insurance; it's easier than you think to wind up in a car accident or trip down the stairs.

You can save money by getting quotes from different insurance providers to find the lowest rates. Also, by taking daily steps now to keep yourself healthy, like eating fruits and vegetables, maintaining a healthy weight, exercising, not smoking, not consuming alcohol in excess, and even driving defensively, you'll thank yourself down the road when you aren't paying exorbitant medical bills.

#8. Protect Your Wealth

If you want to make sure that all of your hard-earned money doesn't vanish, you'll need to take steps to protect it. If you rent, get renter's insurance to protect the contents of your place from events like burglary or fire. Disability income insurance protects your greatest asset—the ability to earn an income—by providing you with a steady income if you ever become unable to work for an extended period of time due to illness or injury.

If you want help managing your money, find a fee-only financial planner to provide unbiased advice that's in your best interest, rather than a commission-based financial advisor, who earns money when you sign up with the investments his or her company backs.

You'll also want to protect your money from taxes, which is easy to do with a retirement account, and inflation, which you can do by making sure that all of your money is earning interest through vehicles like high-interest savings accounts, money market funds, CDs, stocks, bonds, and mutual funds.

The Bottom Line

Remember, you don't need any fancy degrees or special background to become an expert at managing your finances. If you use these eight financial rules and financial tips for your life, you can be as personally prosperous as someone with a hard-won MBA in finance.
