If you try to do the "right" things in your life, you put yourself in a better position to recieve positive reinforcement. However, these things can be different to everyone.
For instance..
Joe Blow wants to be a better drug dealer in order to make more money to take care of his fam, he's well aware that dealing drugs is a bad thing. Bad karma?
Todd Bod is in the same situation but is completely convinced that it's a good thing, a service that he provides to the people who are in need. Good karma?
