I hope you find a church you feel warm in. There is so much variety out there, I'm sure there is a place for you.
Then again, you may choose to simply follow your own lead. Not all Christians are part of a church.
Anyways, Rich + Sucessful does NOT equal a sin.
It is far worse to squander the abilities, talents, and adventures that your life holds.
Personally, if someone were to tell me that being rich and successful is a sin, I'd be wondering "Why? Because you want my money?"
I really like the post about making your own way, not taking what is not earned, and working hard. That kind of attitude can never do you wrong.
