It's doable, and CS50 is a great place to start. You'll know whether or not you're cut out for it once you get to the more difficult homework assignments. Don't give up just because you can't solve them immediately though, it will probably take some Googling since on-campus students have access to TAs and classmates for help when they get stuck. Learning by doing is usually the best way to get the material to stick though. If you can work on your own side projects or apply what you've learned at work, that might help you progress a lot faster.
