I'm more on the bio side, but didn't really have a mentor until I was 35. In retrospect, here's what I'd do: A) have low expectations, so it's easier to define early success and build motiviation, B) be willing to do work for free, as long as it is mutually beneficial, so likely research with no clear financial incentive C) go to where the mentors are: local universities and corporations and research institutes with open campuses. D) at said campus, find some old person sitting alone at lunch. Ask permission to join them. Strike up a conversation. Rinse and repeat daily until you make some connections, find some mutual interests, and pursue them. This has, in my case, led to actual projects, where they formally sponsor me, I get campus badges (I'd like to think I have a fairly enviable collection of ID badges), and and go as I please. This was especially helpful in residency when I needed a place to study on the weekends, but the thought of returning to the hospital campus on the weekends made me nauseous. Especially as an iOS freelancer, you need nothing more than a laptop, right? So just work there until lunch. Or after lunch, whatever. I'll bet you can find an accessible power outlet and wi-fi in the same spot if you walk around for awhile.
