PEOPLE PLEASER

Recently, I realized that I am a "people pleaser." I really hate when people are mad at me, so i'm usually the first one to apologize and take the blame.  Another example, I cant say "NO" usually. If someone asks me to do something, I almost always say "yes." Just to please them, even if I didn't want to or agree with it. I also, avoid conflict and just want to maker everyone happy with me and around me. I don't know, if its because I have low confidence or what? Anyone else a "people pleaser?"
