I moved from finance to law 15 years ago, after 10 years in finance. Probably would have said successfully except tomorrow marks the end of the legal phase, at least in its current guise. I have set up a sole practice to work from home for a couple of select clients, but after having been responsible for about 40,000 conveyancing and other property transactions I might say I was (am) somewhat burnt out too.
The new work I will start (the client work will be a sideline really) is with a group of people who have put together an IT package for my industry! Unlike you Stubbornways and Crutch, I won't be actually working in IT though, but its sort of ironic in some ways.
