I just had to post this quote from here:
As the Internet and a connected culture places a higher premium on authenticity (because if you’re inconsistent, you’re going to get caught) it’s easy to confuse authentic behavior with an existential crisis. Are you really good enough, kind enough, generous enough and brave enough to be authentically a hero or leader?
Mother Theresa was an atheist, filled with self doubt. But she was an authentic saint, because she always acted like one.
You could spend your time wondering if what you say you are is really you. Or you could just act like that all the time. That’s good enough, thanks. Save the angst for later.
