I went to college for a few semesters but never learned anything there. I was studying photography but realized that I knew more about photography than they were teaching me by then anyway, so I decided to move to the mountains where I could ski and take some photos of nature which is what I really wanted to be doing anyway. I learned basically everything I know (in an academic sense) from online materials and college course lectures on the YouTube.
I re-enrolled in classes this summer, but my econ teacher doesn't know what she's talking about (didn't know a differential equation after she wrote one on the board, climate science denier, market fetishist, etc) and my bio class is the same one I took in 9th grade, so I'm not going anymore this summer and got a job on a campaign to prevent the over-use of antibiotics on factory farms in California instead (which you should all be concerned about BTW, because it causes the evolution of bacteria which are basically invincible and live on and in the animals that become your food, and if one bad batch gets out we won't have the drugs to treat you or anyone else).
Never stop educating yourself though, college or not. MIT open courseware puts some great lectures on YouTube, as does UKMC, Stanford, UC Berkley, and a lot of other great educational institutions. And always, always, READ BOOKS, DO MATH, and WRITE YOUR THOUGHTS down often to analyze them.
The only real downside of this method is that you don't get a degree (although apparently with MIT OCW you can submit the tests online and get course credits, something I haven't looked into yet), but you also don't get any student loan debt (which you can't free yourself from in bankruptcy, and is keeping the many recent college grads in the states from being able to buy homes). My experience in the "real world" has been that a lot of the kids with the degrees and the debt are working side by side with me at "low wage jobs" (which is a descriptive statement, not a normative one. Ski instructing at mammoth actually paid quite well, also).
Don't go to college if you don't know what you want to do with your life yet, and don't pretend to know what you want to do with your life if you don't just because your friends, or your family, or society, wants you to, or acts like they know what's good for you better than you do. It's your life, don't let anyone else tell you what you need to do with it. Always be willing to help others, but never let them rule over you, or dictate what path you take. In America at least, unless someone else is paying for it, stay away from college for college's sake. Work a job. Live your life. Make friends (try to avoid making enemies, but if you're doing anything right you will at some point). Have some lovers (use condoms and get tested regularly). Allow your heart to be broken because it will only be stronger after. Go somewhere, see something. Have a few experiences and figure out what you're passionate about, because what you're passionate about is what you'll be skilled at, and if you try to force yourself to be passionate about something which you are simply not, it won't last and you will fail. You may still make a lot of money, but you will resent yourself and your money because of what you did for it, who you became to get it. You'll dream daily of what might have been, if only you had not been too afraid to lose what you "had" to find who you were. You will become a slave who pretends to be free by convincing yourself that you love your chains.
Don't chase after money, seek enlightenment and all things will follow. Seek it wherever you are, wherever you go, and in all things you do. The entire world is a classroom, sometimes you'll be the student and sometimes you'll be the teacher, but always make sure you understand the lesson.
You have material needs, but they are not as vast as you've been told they are by the world, and your desire doesn't have to be directed where the public relations industry wants it. Never let anyone else define "success" for you. You aren't a "consumer" or a "producer," a "maker" or a "taker," you are you, and no one else. Your life is your is your movie. You are the writer, directer, casting director, star actor, editor, and the only audience member which stays around through the entire thing, so make sure that you're happy with it when the credits roll.
Live in doubt, and always question the answers.
