I actually started something new, managed the product, a whole team, did a fair bit of design, promotion/press, successfully exited, all sorts of stuff that doesn't really fall under "Objective-C developer." You would be perfect for a startup where that skill and experience mix is often desperately needed. But you are burned out. (Which is OK as long as you don't stay burned out.) So do you want to teach? Join something like Y combinator but as an advisor. (Can you join without dropping most of your financial gain? Can you drop a big chunk and still have enough left to be comfortable?) How about go into a wildly different filed, something you have a kernel of interest in but have never worked in, forest management, trapeze artists, C++ developer. (One of those suggestion was a joke.) Or travel. (Just enjoy life for a while!)
