Are You Plagued With Self Doubt?

i think that having a bit of self doubt could save us from really bad situations, such as unnecessary wars. I can't say enough about how, in my own life, the need to be humble, to even have feelings of self doubt have been helpful. But it also has keppt me, i think, hungry to continue to work hard to prove myselfd  When you get to the point where you stop wanting to prove yourselfand you're no longer hungry and motivated, i don't think that's a very good place to be.
