With the exception of the "profession" majors (engineering, Medecine, Law, Sciences) college is much more of a social education than an academic one.
Learn to interact and enjoy people from different backgrounds. Be able to speak competently on a variety of subjects and learn what kind of people and activities make you the happiest. If you dont go to college you wont be exposed to so many different tthings at such an early age...and quite frankly you will be socially stunted. I can immediatly tell who has a college education and who doesnt within minutes of talking to them. Doesnt mean they arent great people, with great people skills, who are witty and smart. But more often than not, they only recognize the social and cultural norms of their current immediate surroundsings, which leads them to appear ignorant and narrow minded.
Basically this is the first time on your life where you have had to do something neccessary that you really didnt want to do and was pretty difficult...so you are throwing in thhe towel in the hopes that the grass is greener somewhere else.
Why not suck it up for 2 more years, meet some cool people, get a piece of paper that will make it exponentially easier for you later on in life, and then when you graduate go do whatever it is you are thinking about doing now? A degree isnt neccessary to be "successful" but it allows you to have WAAAAAAAAAAAAAYYYYY more options to be successful in life. I personally became a Civil Engineer because i can make an very good living and my profession is needed quite litterally everywhere- meaning i can live in really cool places and do the things outside of work that i love doing, and raise a family all while never having to worry about money.
Not to mention that by dropping out, after spending $30,000.00 of their money, you are giving your parents a big EFF YOU!. Dont act like a spoiled child. Be an adult, suck it up, complete college, and then go do what you want...or payback your parents for all the money they have spent on you at college.
