When I was ~20 years old, I wrote myself a letter from the future me. 

This letter contained the values, principles, guidelines I wanted to practice to create the most epic life possible.

Then I'd read it whenever I got off track. 

8 years later...

I didn't live up to all of them (fell short in some areas, completely Fd up in others), but man was this helpful. 

Give it a listen and see how it impacts you?
