I want my last sentence to be powerful and to convey
that I have never or will never back down fom challenges because if I had I wouldn't have made it this far
Does what I have work, is it grammatically correct, any suggestions on new sentences, keeping it as is, or revisions
After all, I am not someone who succumbs to challenges, with a heartfelt commitment of never becoming.
It seems like the with is throwing it off to me.
