how would anyone boost their self esteem???

Speaking from personal experience, you just have to change your self image. If you think you have too much acne, splash a little make up on and see if it makes a difference in how you view yourself. Not happy with how your hair hangs? Change it. And if you truly have low self esteem, you tend to walk with your eyes downcast, as if you're not worth others seeing. Stop doing that. Hold your head up and meet people head on. You would be suprised how much better you feel when you trust urself
