I am not a teen, but the day I turned 13, I decided that I wanted a car.
For 3 years I did part time jobs for neighbors, but my real advantage was that I was also what is commonly known as a musical child prodigy (turned pro at 6), so I performed and gave 75% to my managers (parents... lol) and saved 25% into an account that they managed for me.
3 months away from my 16th b-day, my father and I walked into a Ford dealership and *I* signed the papers to a brand new Mustang Cobra that I paid for in cash that came all from my own work. I had no license, so I could not drive it (for 3 months), but it was 100% paid for and as a b-day gift to me, my parents paid my license plates and 1 year of insurance.
Point is, there are many ways for a young motivated enerpreneur to make money.
Another example? This 11 year old went to his dad to borrow $100. His dad was like "what??"... anyway, long story short, he put that $100 on a single domain name. That domain name was bought from that little kid for $250,000.00. Not bad for a 4 month and $100 investment.
Now, unless the lawyer that completed the legal transactions on behalf of Pepsi Corp. lied to me, this is a true story.
As I said, there are many ways for a young person to work and save up money. I applaude all the younger ladies and men that can do this. Instills a nice sense of value to work ratio.
