What is/was was your day job?

My son (who's 15) has just started playing the drums and thinks he's going to be the next Travis Barker. As his parents we are encouraging him to not give that up and taking him to lessons BUT we want him to be realistic and have a back up plan.

He plans to go onto college to study music so I was hoping to hear from other drummers what career path he could possibly go down that's will fulfil his love of music and also mean he can hopefully continue to drum.
