Sometimes it's best just to concentrate on what is important, you have acheived a lot with StackExchange, it take a sensible chap to realise what you have and its a large sacrifice, but I have no doubt you will not regret this and in time go onto other great things. You are an inspiration to generation of coders/engineers, good luck with your new focus, I am sure it will be more rewarding, but just as hard work.
