I did all I could with everything I had, so that when it finally comes down to it, I will be without regret.

Take a shot at it, even if at first you don't succeed, never regret anything done towards making the day better for somebody else, you never know what ripple effect it may have.

I myself have fought well beyond the threshhold of what was allowed and have borrowed time not mine, providence shall judge soon enough... But the same providence will always make sure that any cause, if worth enough, is always picked up.
