Is being naive a bad thing?

Yes it is bad to be naive because it takes you away from being yourself and making your own decisions, plus it can get you into a lot of trouble with people in the future. You also must never do something or try to be someone else because of the things they tell you. That shows a big lack of self confidence and it makes you look weak. People take advantage of naive people because they can get them to believe anything. So try to break this naive trait you have.
