God may allow His servant to succeed when He has disciplined him to a point where he does not need to succeed to be happy. The man who is elated by success and is cast down by failure is still a carnal man. At best his fruit will have a worm in it.

How does it happen, Maecenas, that no one is content with that lot in life which he has chosen, or which chance has thrown in his way, but praises those who follow a different course?
[Lat., Qui fit, Maecenas, ut nemo quam sibi sortem,
Seu ratio dederit, seu fors objecerit, illa
Contentus vivat? laudet diversa sequentes.]
If you come to fame not understanding who you are, it will define who you are. It shouldn't change you. If you're a jerk, you just get to be a bigger jerk. What fame does is magnify who you are and puts that on a platter for the whole world to see.
