Go to school. The prop landscape and the industry is changing right now. Better to wait a bit to see what shakes out before you dedicate yourself to prop. A college degree (IMO) is never wasted time.
You could always get a job emptying the garbage cans or stocking the coffee room @ Brokerage firm. GET A DEGREE, HINT...the medical field is always hiring. You can always trade down the road, markets are not going anywhere. When you are washed up and 35, you will not want to go back to school, just get a degree now!
Whatever you deceide to do, if you choose to work full time I think you should attend college also. Even if it is only one course in a semester, you are in school while working. DO it at nights or weekends or online. If going to school does not get you into serious debt I would say go study something that you are interested in (full time). That way you will enjoy it more.
A college degree, especially a relevant, useful one, will stay with you for life. Trading will always be around. My advice is get the degree and follow the markets 1-2 hours a day on the side (more if you can spare time from your studies). Open a small account and trade for 3 years part-time. Keep a diary of your progress. That will be immensely useful to you and has pretty low risk so long as you don't go crazy on leverage.
All degrees are useful in the sense that many jobs require a bachlors of any major. Nevertheless, if you have a field that you are interested in you should pursue the"useful" majors. Perhaps, Computer Science, Math or anything bussiness related would be useful in finance.
A few guys I met recently from Jane Street have Financial Engineering or Math degrees. I guess University of Chicago and MIT may have helped out!
Top payees are those in dentistry. AFAIK, according to my advisor at CUNY, all I need is a bachelor's in any bullshit along with some teen credits in premed to get accepted to a dentist school. 3 more years and you get your license. Then you can throw as much money on trading as you want. After being through some hard times, I can exclaim with full confidence that undercapitalization is in top five of an aspiring daytrader's worst enemies.
Stay away from finance altogether. The only business-related degree worth a damn is accounting. Also, look into engineering (I'd suggest civil or chemical).
I have a finance degree and the above quote is very true. If your actually interested in finance you will learn a lot more by reading then from the university classes.
I don't know who your advisor is, but s/he is way off track on dental school. It's every bit as competitive as med school, and even more work. Check the GPA's and DAT scores recently. I attended med school, and the dental students take many of the same first year classes with the med students. In addition, they have all these special classes just on teeth, build models of teeth, and a lot more. Tests every week, an 8-5 school schedule and study at night. "all I need is a bachelor's in any bullshit along with some teen credits in premed to get accepted to a dentist school." This couldn't be more wrong.
