Some good ideas. However, going to college is not all it's cracked up to be. I'm not sure why anyone should waste their money on the "college" myth. What does a Bachelor's degree get you? Nothing. It is merely a barrier-to-entry.
However, if you wanted to get a bachelor's degree that is worthwhile, get an Engineering, Nursing, or some type of vocational degree. Stay away from Academics: Hard Sciences such as Math, Biology etc., Liberal Arts, Business (Frat Boy Party) School, etc. In Engineering, don't believe any of the rubbish Engineering Professors teach you about Intellectual Property. Very few of them understand how innovation or creativity in the market works or are stimulated.
I finished my Auburn University Electrical Engineering core in 1.5 years (after previously fulfilling the all the core brainwashing classes part-time), but I would recommend taking longer so as to not kill yourself. If you're a good test-taker like Gary mentioned, you may be able to do it fast. I'm not, I learn by doing, not by regurgitating on a 50 minute test.
The other issue is, when you attend engineering programs at schools like Stanford or MIT, you may run into many energetic undergrads working on their own startups companies. However, in most cases, at your typical State school, you wont learn entrepreneurship skills. But nothing stops your from learning or starting a company in college yourself. While in college, when the risks are still low, form some startups. Don't be afraid of failure. You will look back on your life and appreciate it later.
