This rings true with me. Although yet to hit the heights that you have, I treat my job as just that. Not a matter of life and death. Its especially true when you realize how quickly you will be replaced when you go.
I left my job after 3.5 years back in December. Leading up to giving my notice was the most stressful time in my career. Then, after 15 minutes of a professional conversation (and then 3 hours of friendly chit chat about starting my own company) the stress was gone. It's not a big deal. Two weeks later, I was free. I'm still on great terms with them, and even get jokes from my old boss about coming back some day and ending my 'poverty strike.' :)
It's really not a big deal to anyone but that fearful little voice in your head.
