if you can pay for college, you could pay less to not work or go to college. and still party and have sex, if that's what you care about.
Nobody is measuring the importance of school, on how much fun you have with it, but what I am saying is that you can learn a lot, and yet have a great time, and yes even fun. Unless you are sociophobe, scrooge, or something, most humans want some fun on the side.
I thought CS was not that difficult, so I decided to minor in math, which I found it not that difficult so I challenged myself even more, and I decided to minor in Physics, and here I met my match. A hard ass professor, that would teach a lot, but it was almost impossible to get an A. My first ever class, where I felt no matter how much effort I put into it, I couldn't get an A. It taught me about humility, and learning my limitations.
And, yes, I did all that, plus lot's of volunteering, helping with alumni affairs, while having a part time job (washing dishes, and then just a lab proctor) at the same time.
There is nothing more awesome when you learn a lot, and yet can have fun and get laid at the same time.
To all you say that college is waste of time:
1. Maybe you should study something that you are going to get a great return out of it, or it will be challenging enough.
2. You might want to check if you have problems getting socially adjusted.
So, unless you quit school and become a millionare by now, you have no cred on saying college is a waste of time. College is a waste of time for many, b/c they don't use it. To those that are smart enough, it is a great learning experience. To those that think are too smart for college, maybe they are not taking the right/classes or programs. If you are a genius, what prevents you from finishing it in two years, get a masters, get a phd. and become the next albert einstein, invent cold fusion, a cure for H1V or something great? You can do that in college. It allows very smart people, to have access to great equipment, grant money and other resarch, things that you probably wont have in your own basement.
Those people that skip this, are soreley missing a great experience of their life.
Remember, work will be there for the rest of your life. Don't just rush into it. From 24 to 64, that's 40 years or working for most people. you can start your startup just as well as 25, as you could at 20, but probably you would be much smarter at that age.
