You sound a lot like me, only I've already been in my current company for a smidge over ten years. I don't see the experience in another company being any better than I have here (sure I can get more money but at the loss of work/life balance and personal stress levels).

Also, being around longer I've built up a nice backlog of benefits including equity and a metric ton of vacation days. I would have to give up a lot if I moved, and most companies I've spoken to won't match my deal for a new hire.
