 I hate to burst your ego but most people have no fucking clue about this.

Not true.  I know many ppl who maximize 0 percent and rewards, but we all travel for work.  You can make thousands of dollars per year if you travel for work for example and book on certain cards.  I also make hundreds per year in cash back rewards by running transactions thru a credit card and keeping a zero balance.  If you're disciplined you should do it, just never carry a balance.
