When choosing the person or people you're going to build the business with, be careful. Even if someone is your best friend, it doesn't mean that you will partner well in a business operation. Start it with a reliable person. Things to consider when choosing your co-leaders and support cast include:

Does the other person complement your weaknesses? Or do both of you bring only one set of the same skills to the table? If the latter, be wary as you can have too many people doing the same thing while other things are left unattended. Do you see eye to eye on the big picture? Arguments about the details are a given, and are important for getting things right. But not Seeing Eye to eye on the big picture, the real purpose of your business, can cause a split that may be irreparable. Be sure your team cares about the and buys into the purpose as much as you do. If interviewing people, do some reading on how to spot real talent beyond the certifications, degrees or lack thereof. The area an individual is educated in is not necessarily the area they are most talented in. An interviewee may have a background in accounting for example, but their experience and your assessment of them indicates they may be a better fit helping with marketing.
