Undeniable truth: Life requires confidence. There’s no trendy hack for faking it and no pill can substitute for it. You have to believe way down in your bones that, yes, you can kick ass and succeed.

Except for when you don’t, because some days you won’t.

Some days you’ll trip, fall and fail. You’ll beat yourself up for a job not well done. You won’t feel brave, strong and smart. But you can’t let the bad days overtake the good. You’ve gotta shake it off and get back up.
