If you find college to just be a joke, it probably means you're either at the wrong college, approaching it the wrong way, or both.
My suggestion is to pick a general field you're interested in (e.g. CS), get a good survey of different specialities in it (like AI, machine learning, databases, compilers...etc) and choose the one you like best. You'll probably find it much easier to focus your curiosity on one speciality within CS, and it will probably be easier to do something interesting and non-trivial within some speciality like this.
Coincidentally, this is exactly where college is great--it gives you a nice structured overview of a bunch of different fields within your chosen subject and also lets you dive more deeply into whatever interests you most. College also gives you the general background needed to learn about the more specialized material--you're forced to learn more about subjects like math and EE than you would learn by yourself, which will help you in doing something non-trivial.
