### Re: The Free Will Straw Man

There's also another straw man that I'd like to point out: responsibility.

No, nobody thinks this way. It seems that what you are positing is a deterministic clockwork universe in which everything could be traced back to a root cause. Knowing that cause would let us predict the entire future, including peoples' actions. Are you kidding me? It's called determinism, and it'...

If you really want to shatter your self-confidence, check out mathoverflow.

But really, there's not much point in comparing yourself to others at this stage in your education. Just keep giving it your all and studying the things that are interesting to you.
