I did a lot of things that I regretted and I certainly paid for my mistakes. You have to go and ask for forgiveness and it wasn't until I really started doing good and doing right by other people as well as myself that I really started to feel that guilt go away. So I don't have a problem going to sleep at night.
If you want to achieve your dreams you must follow them and the best way to follow them is not to think about wanting to be very rich but to think about doing something that you really want to do.
