Meh, do what you want and you'll find success. Yeah there's a lot of money in finance but generally that's equated with an insanely shitty work/life balance that you don't get through for years and years.
I hate how PE is considered finance because it's really more business-related than anything; it's just considered finance because it's an investment vehicle for the LP's.
I want to go into PE because I like the idea of being involved at the top levels of a business to help it grow. I'm also considering C-level management, but then you don't get the diversity of experience as you do with PE. If I think of a good idea I might start my own company, who knows.
