Dealing with self esteem problems again

Some time that I feel so frustrated about my current research progress, I tell myself: Maybe I've picked the wrong topic that I can not really be creative about it. Maybe I should have chosen something different closer to my intersts. But later (in low self-esteem mode), I tell myself: But what is really the area that I can be more creative? Am I really a creative person after all? I'm not sure about the answer. Maybe I should push myself with the creativity issue that much.

I admire creativity a lot, maybe even more than diligence. But it's a wrong belief, because on average elites are minority of the people and healthy society is the one that promotes deligence rather than elites.

PS: From this post, you can imagine that the joy of passing the comp exam is long gone and I'm back to practical PhD issues ;-)
