squiggy: I too know where you are at. I was there. Lucky for me, my girlfriend Amy saw what needed to be done and basically forced me to make the change. I couldn't be happier for it. Take that time to get yourself ready, find that place you want to be, and go for it. The challenge is there, and you can have it without sacrificing everything else.
raph mentions the trip from Half Moon Bay to Pacifica. I love that stretch. I often just drive it for the sheer beauty, maybe stopping at the North State Beach in Pacifica for some time by the waves. I've only once driven from CA84 to Pacifica, though I suspect I will do it again.
I can imagine how beautiful walking it would be. I don't know that I'd ever find the time myself, but I wish raph all the luck and good mental state he can get.
