Two words for you: "Networking Investment"

In my opinion that $250 would be better spent on throwing a party or paying for lunches with some upper class-men. Maybe find a fraternity with finance majors or the business frat (Delta Sigma Pi comes to mind) and join. Many fraternities (if good at recruiting) will pair you up with similar majors during rush to get that 'in common' aspect with a brother.

Get a job this summer (maybe at a local bank or credit union or a stock broker assistant). Don't apply to 3 places, apply to 30+ places. Don't give up until you have something. Don't use the excuse of "Well it's only a 3 month job" to not look or stop looking. Did you participate in FBLA in high school? If so, I'm sure some of those kids and parents may have connections in the community. Sometimes its who you know, not what you know. You can learn the job as you go along, especially in entry level positions.

So go make some more money. Save up and be ready to hit college looking for networking opportunities. Join the campus investment club or start one with some of those frat guys if there isn't one. Find local businesses willing to invest in the club. This alone could turn into your biggest long-term professional network if done right.

Use your money wisely though. Buying some crap stock hoping to make $15 is worthless at your age. If you play your cards right, in 4 years you'll be playing with much larger stacks of money or work for someone who does. Then you can worry about how to invest all that mullah you're banking AFTER you've got the education and experience to put it to use.

So again, try to turn your current money into a 'networking investment'. Get to know people that can help you in classes or as a network for future job potential. Don't be the douchbag sucking air out of them though. College is also about having fun so don't forget that aspect too. Get to know them on a personal level and show genuine interest in their daily lives and hobbies first and networking through their friends and friends of friends will come naturally.

Good Luck, I'm sure you'll do great! It's college man, have fun with it!
