Ask HN: Do you ever feel inadequate?

I am a postgrad student that works in a local compsci consultant company. Throughout my academic and brief work career i've met plenty of brilliant people, people that where elastic with their mentality, mathematicians that could prove anything they wanted to, coders that had a keen mind for problem solving... and then there is me, i have a few skills in regards of programming, i can sort of compose some music, i can structure a few things in a mathematical proof but... i feel quite inept. I know that those things don't define me as who i am but... well... i feel like they are necessary in my career path (except for the music production, that is for me :D) Does that also happen to you people?
