Always remember that you only have this life. And no matter who you are, we're all equals as humans. Wherever we are in life, we can't bring any of these with us when we leave from this world. So why not take chances? You have nothing to lose anyway. What he can, you can. But what he is, has nothing to do with who you are and want to be. If he's more wealthy, silently laugh at him that he's going to lose more than you when both of you die, but don't be evil.
