Why does going through Carol Dweck's Mindset again feel just as much like an epiphany as the first time? (Apparently, it didn't stick, and I had just reverted back to my stubborn fixed-mindset ways.)

Focus on growth. Recognize and learn from your failures -- don't let them discourage and define you.

Stop moping. Think instead, "What am I going to do about it?"

Maybe then you won't feel like you have to keep hiding different bits of yourself from different people.
