I can relate this to part of my experience picking up stuffs and putting down in a couple of weeks.

Sometime I can feel that I'm in this or that because of some ego or future bragging and they dropped dead quickly.

But then again this probably roots from my childhood as I tended to appease to my teacher or parents to do a lot of things I don't enjoy. So it's really difficult to tell nowadays if I really enjoy doing this or not.
