When we are born, we need help. So, it is very important to be liked by your parents or anyone around you. It is very critical to be liked for just surviving. So, we are eager to be liked by others.
Once, you become an adult, you don't need to be liked anymore because now you can do things without much help by others. Being liked is good but not necessary.
You may need help sometimes, but still you don't have to be liked. People help you because of your vision, not because of you.
If you don't like you, you can do something about it. You can be whoever you want to be. It may take some time. So, what? If you are not you, everything goes wrong. You need to be you. Quite simple.
