This thread has some great advice.
I think the decision comes down to a personal one, based on everything that's been said in here.
Retirement pay is pretty nice, I gotta say. I got my first retirement paycheck last month, I did nothing but golf and watch soccer. I've interviewed at a couple of places and am still waiting to hear.
But, here's where retirement sucks: Honeydew list, I get a new one every day. Even with sequestration, I still see aircraft flying in the pattern, remembering exactly what it was like. That kind of hurts. I see former squadron mates on Facebook and know I'm no longer a part of that camaraderie.
It's a difficult decision, I could've held off my retirement until October, but I made the decision to retire.
Whatever decision you make, it'll be the right one, even if it may not seem like it at the time. If you go in with that thought, you'll be happy.
