Do you believe that people can be anything they want in life?

I have to believe that because believing that makes me different and being different makes me strive to be.

No.... even as our own aim, focus, mindset and efforts do have much of a role in determining what we are, there is always that element of a bit of luck or misfortune or timing that either seals it or spoils it.

yes, if they apply themselves and have a bit of good luck.

Everyone has limitations.

"You can be what ever you resolve to be." ~ Stonewall Jackson with the key word being 'resolve'. You can't just 'want' it, you have to be resolved to accomplish it. And yeah. I'm living proof.

To a degree yes, but unforseen events and people can alter that.

Definitely not, circumstances happen and it can render a person totally helpless.

Yes and no.

Yes
No
Maybe...
idk I say leave it up to fate
