I left the USAF AD in 2005 and joined UPS. If the USAF offered me $10 million per year to go back to active duty I would not take it. Money isn't everything and you have to do what makes you happy--at least not do something that makes you miserable.
There is a lot to be said for not worrying about a PRF, OPR, your next assignment or if your commander knows how great you may be. Not to mention being deployed half the time and having your kids not recognize you when you return. The USAF is a strange animal right now and all you have to do is look at the crop of new BGs. CC from McConnell circa 2004-2006 is soon to be a general YGTBSM!!
