Andrew could a) do charity work under the radar b) find a real job under the radar.
Charities wouldn't likely want him for any public role, but he could do private things (although not anything to do with minors). He could find a real job where he could use his talents (whatever they are). Even if he only worked two days a week, it would give him some purpose.
In order for him to do either of these things, he would have to do a lot of soul searching, swallow his pride and buckle down and do a day's work. At his age, when people are retiring, it isn't easy to find work, but there are lots of people who need tutoring in ESL (again, not kids!), for example. He would need to come down off his high horse and get his hands dirty. It could be done if he wanted to.
