I begrudgingly had to take classes I had absolutely no interest in. The schools would offer classes with a clause if the class filled-up before you could get it of : 'what do you want as a secondary choice if you don't get your first choice'. I begrudgingly now admit that every one of those classes have since become useful over the course of my life. If I went back in time, I'd tell myself to get the most out of every learning opportunity I had, even though at the time I had no interest in them. The information you get will come in handy later in life.
