There are some things that one does, not because he/she likes doing them, but only to prove to the rest of the world that one is as good as many others and is not a weakling. One may not hate doing what he/she is doing. One just wishes that it could be done in a less grueling manner. It is easy to advise someone to follow their heart. Easier said than done.
One always looks for approval; for acceptance.
It is but human nature.
