Why Force It?

Why do people constantly try to force others into situations they don't want to be in? Or into doing things they don't want to do? I'm constantly being surrounded by people who are trying to turn me into someone I'm not by forcing me into doing things I don't want to do. It's so frustrating! Especially when I tell them I don't like it, or I'm not good at it, or otherwise make it plain (to me anyway) that I have no interest in this, yet they persist in forcing me into doing it anyway!
