How do you improve if you don't use rejections as reflections to find flaws in yourself? As in, how do you improve if you don't personalize rejections?

The idea is better served as to being tenacious and not giving up even after rejections. A lot of times we take rebuffs as negative validation not to keep going or to have it drag us down in depression.

Don't expect rejection but learn to cope and live with it.

Also--especially dangerous now that I'm reading some of these comments--learn not to be so high up in the clouds and deluded in thinking you're above reproach or criticism. You're not. Learn to cope with rejection so that you're not just getting carried away with manic dreams.

Life is learning the balance.
