Thing is....YOU must be the one in life to toot your own horn, cause ain't nobody else gonna do that for you.
Especally bad, is being a teen....Your self-image is usually tied to what others think about you & how they treat you. But once you get into your young adult life, you realize just how fake that all is. It don't matter in the least what other people's juvenile opinions of you were....The only thing that REALLY matters is what you think of yourself.
Other people come & go in life, but you are always with yourself your whole life. To survive in life, you must become your own best cheerleader.
