You don't have an ego, you *are* your ego.
If you got really popular and had lots of approval, you would realise that approval and popularity are pointless and empty too, and you would be back at square one all over again. The ego wants popularity to boost itself up, but more importantly it wants drama and conflict. The feeling that there are problems all around you and the thoughts you have that the world *should* have a point are all from the ego trying to latch onto something, anything, to make itself more real.
The reality is people who are happy and living their lives have the same problems and the same concerns you do, they are living in the same empty life. They have overcome it, or embraced it, and used what they know and the advice other people give for fuel to push them forward.
You say that you discard it because they don't work for you. Things that work for other people will tend to work for you. People tend to be all the same, you really aren't that unique.
