My recommendation for the day? Let your self be flawed.
Do some things badly. Fail to do other things entirely. But be absolutely awesome at what matters most.
Play to your strengths and put them to use as fully as you can. Don't worry about filling in every chink in your armor, shoring up every weakness and improving every shortcoming. The days are too short to do all that.
Do what you can do. Be great at what you can be great at. And don't spend too much time on all that other stuff.
