Start giving more. One of the best ways to build yourself up is to help others. Giving someone else a helping hand is a sure-fire way to feel needed. Every week or month, schedule some volunteer work at a hospital, nursing home, animal shelter, or anywhere else you might be needed. Spend some time helping a friend or neighbor who is ill or has other serious problems. Giving of yourself to others may help you view yourself in a more positive light and gives the people you're helping a chance to let you know just how valuable you are.
