Overview
If you want to volunteer your time, do it for the right reasons. Don't just do it because someone important asked you to. You cannot brag about being selfless if you're doing it only to look good or impress someone. Besides, there's no point in helping others if your true goal is to help yourself. Make sure you are honest about your motivations. Everyone will respect you a lot more if you are true to yourself and do what you really want to do.
