Absolutely dude. On the flip side of self-importance is that self-doubt, which I've had far more issues with than the former. I've tried to accept self-doubt as a natural defense mechanism that we have though, and it's okay to let it exist, just not to dictate your forward actions. It goes with the mantra that I live by almost obsessively that identifying your weaknesses is so much more important than identifying your strengths.

But like anything, moderation is key. :)
