The duality of too much and not enough. I have heard both often. I'm too kind. I don't stand up for myself enough. I'm too sassy. Too friendly. Talk too much or not enough. Too smart. Too dumb. It goes on and on.
Everyone is individually a work of art and as any artist knows if you show a work you created there will always be a critique of what can be changed. It is a never ending cycle and it will never be perfect enough to suit everyone. So be unapologetically you. Be brave. Confidence in yourself is one of the most attractive things.
