The path to success involves a lot of how you deal with failure.
Do you believe failure to be a (by)product or do you view failure as an indictment on identity? A simple litmus test:
When something you've been working on/betting on doesn't work out as you planned/hoped, what is your internal monologue?
1) Well, that failed.
2) Well, I failed.
Think about it. The former perspective assumes grace and possibility and leads to a motivation to try again. The latter perspective blinds us to possibility and keeps us from confidence and hope.
Where do you land?
