Go against regret
There are some things in the world you'll regret you couldn't have the courage to do. Find them and do them.
How I use it
Ask yourself do you want to regret anything. Or when do you usually regret. For me it's when I'm older and looking back at my life and see a version of my life that could have happened.
Example
Very busy day. Night in your home. You promised yourself that you'll run today. But couldn't find time. Now go further in time think about tomorrow yourself. Staying at home or running. Which one would make you regretful?
