How do you lower selfesteem?

Why would you want to lower your self esteem. People spend a life time trying to heighten their self esteem. Now, if what your talking about is looking at yourself as better than others in a human sense, then that's another issue. If this is the case, I have a philosophy about this. Its called appropriate humility. I always keep humble even when elevated, and here is the reason why. Because I know, whatever I have, God can take it away from me at anytime. You can have appropriate self esteem, without the loss of character. Then teach others to do the same.
