If that were the question, my answer would be "my whole life thus far". XD lol
As for the original question, I think that I'd do just about anything that didn't shatter my sense of morals or self-worth. Damage it slightly (to where it can still be fixed/recovered), perhaps, but shatter it, no.
There's no point in being "successful" if you hate yourself. You'll just be miserable, and I consider that to be a failure. True success comes with happiness, and then with monetary gain. ^_^
