firstly, I don't think you should care if people like you or not but I can understand, sometimes we care especially if it's someone you like and care about either family or friends or just the people around you, my suggestion is to be your real self and stop trying so hard, another thing is to focus on yourself and try to improve yourself in every field especially the things you like and enjoy, try to build your personality the way you like it to be and take the first step to that by reading books related.
