1. Contemplate/Meditate and  deeply assess what you would do for free and what you feel strongly about.

2. Identify your talents, longings, gifts and skills. Remember to think about the things people have sad about you throughout your life that may have a negative connotation, for example, "you talk too much, you're so cheap, you're always in someone's business, you're always trying to tell someone what to do".  All of these characteristics are nothing more than attributes that need to be channeled in the right direction. They will also be a benefit to you and your purpose. 

3. Align your values. Define whats important to you and compare the list to how youre living your life.
4. Develop a vision.

5. Just do it. You may think that what you are being called to do is risky. Do it anyway!
