Ive been running my own landscaping business since I was 13, now its grown into about 40 customers and I'm still 16. I also work at Main Event as night work for extra cash(mostly used for audio). Plan on going into Pyro-technics after collage, have a customer that is a pyro-techniction and once I'm 18 i can help him set up shows, gain experience, etc.
Also if you're wondering, yes my family is wealthy. However, the only thing i dont pay for is food, water, electric, gas, and rent.
