Another path I suggest would be to invest in a Roth IRA or Mutual Fund. (Google them both to learn more) Contribute to the fund monthly. A mutual fund\IRA provide instant diversification in the stock market. If the fund goes down, don't panic, continue to contribute because it means you are buying more shares at a lower price and it will grow over time. The Stock market averages an 8% yearly return over the last 50 years.
If you start to work in the Corporate world, sign up for the company's 401K. This is similar to a Roth IRA and the company usually matches up to 6% of your weekly contribution from your paycheck, so if you don't sign up you leaving free money on the table. They will take your contribution directly from your paycheck and you don't even feel its missing. One of my friends recently told me he has been in his company's 401K for about 20 years and has almost $1.5M in there now!
Lastly, someone already mentioned to avoid unnecessary spending and bad credit card debt so I wont go into detail on that, but it is very sound advice. However, be very cautious about investing in Stocks on your own. At some point some of your friends will tell you that they made 2 thousand dollars or more in just a few days of stock trading and it is probably true. What they don't tell you is when they lose thousands of dollars. If you do decide you want to trade stocks on your own, do a lot of research, open an account with fake money and practice for 6 months before you venture on your own.
If you focus, follow a good plan and manage your risk, you will do well. The opportunities are there and I'm sure you'll be very successful!
