Mr Phil gave good advice on the investing course.
Getting into individual stocks is the best thing you can do. It will stimulate your interest more than a fund by getting you to look at companies as an analyst should, though many analysts have made up their minds before they look.
Good luck and skill.
The college cource will get you started. It will probably taught by a investment consultant from a investment firm. It will break the ice and give you a some basis to start learning. There will be a bunch of old retired people in the class that know little more than you.
You should not be buying individual stocks you should buy mutual funds.
Got to Fidelity's website and start reading. That's where I started when I was 22.
Buy a fund based on your risk tolerance at first.
As you learn about the economy you can buy and sell sector funds.
You won't get rich quick but you will probably outperform the zero% you are getting in the bank.
Just in case you make some real money in the future and you want a different view , you might think Depardieu.....lucky for my father and i we were 30 years ahead on the concept.
401k is like jail for life , replace that by "offshore" , if you feel guilty, DONATE!
I suggest you save your money the best you can. Don't spent too much drinking but have fun and save time for homework. Save 10% of every dollar you make from now on and use that money to begin saving and investing. Learn as much as you can every day. Don't take college for granted, enjoy it, learn, expand your horizons, try new things(not drugs), and be safe. I suggust you put your money into a S&P fund and possibly buy a few individual stocks. This is a good player here but be careful. Buy low sell high. Good Luck
