The Recipe, by Mark Twight.
When the voice inside says, “no” take another step.
When the voice invites you to quit, don’t.
When you think you can’t go further, bluff.
When you are certain you have given everything you have, when you bluffed and got called, when you went further or harder than you believed you could, and know that in a few months you will look back without second-guessing or regrets, it will be OK to fail. But do take notes.
