Whatever he likes to do then expand on that and don’t give up. Nothing is to small : ) 

 When I was in High School, I got a job taking care of expensive horses imported from Germany. It was my job to fed all of them and that included their medication plus clean stalls and turn them out/ bring in.

 I really enjoyed that job but thought I was a lost cause for doing it because wrongly so I THOUGH PEOPLE WERE supposed to work in offices and have "REAL JOBS" if I had been smarter then I would of had the follow through to see that could of eventually bought my own stable and rented out horse stalls keeping the same job but expanding on the responsibilities with ordering grain and such but been able to make a ton of money in the process. Be true to who you are is my advice. Find your niche and know your strengths.
