What do you get for the person on your list who's itching to break out on her own? With the right tools and tips from pros who launched successful side hustles of their own, she might be surprised at how quickly one can start earning money — and having fun — outside a regular 9 to 5.

“Even if you don’t want to leave your job, a side hustle is an awesome way to make extra money, use your talent in the world, and hedge against an uncertain job market,” says Susie Moore, author of "What If It Doesn't Work Out?", who started her side hustle as a life coach and writer while working as a sales director at a Fortune 500 company. Plus, pursuing what you love outside of work can help you feel more fulfilled and motivated at your day job, Moore says.

Below, Moore and two other entrepreneurs who side hustled their way to success share the must-have books that helped them build their side gigs into fully-fledged businesses.

Whether you're looking for a gift for a marketing executive who wants to do stand-up comedy shows on weekends, an accountant with a calling to be a spiritual life coach, or a lawyer working on a historical fiction novel, these reads will equip your favorite entrepreneur with the wisdom and inspiration needed to make that dream a reality.
