Short List of 4 Tips to Help Define Your Purpose

1. Don’t run away from your past. Use the knowledge you’ve acquired to guide you.
2. Take multiple a personality test. Then google your 4 letters and look for the cazenovia PDF. Tons of info. Typefocus is a reliable one as well.
3. Use the Eulerian Destiny developed by Tai Lopez. You ask yourself these questions. What did I grow up around? What do strangers compliment me on? What have I been doing or learning in the past 10 years? What can I talk about on a Saturday night with my friends?
4. Take the StrengthFinder 2.0 test to find what your are naturally good at. You can only have true success when exercising your strengths.

These help me but I would say number 4 combined with 3 is where I had received the most insight.

Good luck!
