This is a very interesting question, because I'm going to give what seems to be a "too easy" answer. However, while there are classes that are "only" fun -- one extreme -- and classes that are "not fun" and "only beneficial to college and career", most are not at those extremes. I point this out because I've always told my students that "You'll likely enjoy what you're good at, and you'll likely be good at what you enjoy." There's also that very salient quote, "Do for work what you would do for play, and never work another day." Your goal should not be solely to make lots of money or get lots of awards, since those are really indirect and hopefully-effective enhancements to enjoyment. Enjoying your life is your real goal.
The lesson here is that you should spend a LOT of time examining just what it is you can do to combine these things. Your goal is to have classes that are fun for you and prepare you for a career doing something that will make you happy and make your life as fun as possible. Now, as I pointed out earlier, examples at the extremes are exactly that -- extremes -- and likely rare. So look for a compromise that doesn't hit either of those extremes. IOW, avoid "success" classes that are painful to take, and "fun" courses that provide you with nothing useful in the way of skills or experience. My bet is that your high school will have lots of courses that will enable you to do that.
