I've adapted my mindset to think of my job/role as a car lease . Expires in 3 years. I don't get too comfortable, not too attached, tend to live in the moment, enjoy the good parts, ignore the bad ones, think of the next person in my role, stay on the lookout for my next job/role, but not overdo it. I've been able to stick to this, but haven't come up with a ways to enforce it.
