There are two kinds of pride, both good and bad. 'Good pride' represents our dignity and self-respect. 'Bad pride' is the deadly sin of superiority that reeks of conceit and arrogance.
It is hard to feel bad about yourself when you are doing something good for someone else. There are a lot of ways to lift your self-esteem, but making a positive difference in another's life has got to be my best leadership guidance. Serving others and working to add value to them will lift your spirits in a way that nothing else will. Trust me on this one.
If your desire is a 10 but your self-esteem is a 5, you'll never perform at the level of a 10. You'll perform as a 5 or lower. People are ever able to outperform their self-image.
