Whats a good small business to start?

I got a van from m inheritance from my great-uncle (the oldest gay person I ever knew) its a 1998 GMC Savanna nice van. Well anyways I am determined to start a small business. I am 16 and I need something that's profitable enough I can later higher a employee and still make a profit. I have always been a keen entrepreneur I used to do penny stocks with my cousin one time I bought 7 red bulls stayed up 2 days ad earned 800$ and a had a panic attack ever since then I cant stand to work them plus my mo refuses me to do it. So any ideas???
