Of course you have to do what you want, but I will say this: Just about every senior aviator Marine and Navy alike have told me they would give anything to be able to start over and do it all again. That is something you will never hear out of a fortune 500 CEO or other similar civilian counterpart. If you love aviation flight school for Marine and Navy is like living a dream. There will be many days when you are sitting with you buddies amazed at the fact that you get paid for this stuff.
This is absolutely correct. I can't imagine any senior aviator not wanting to go back and relive it all. I would. I left with over 5,000 hours in attack aviation and over 400 traps, made cruises to Westpac, the Med and IO, plus workups in the Caribbean and South China Sea, saw places I'd never visit otherwise, lived all over the US (V Beach, Whidbey, Meridian, Pensacola, Alameda), Japan, Philippines, Puerto Rico. I still miss it.
Granted, there are aspects that suck. That's why only 25-30% of naval aviators stay past their original commitment. But even those who leave, at any stage, will, I believe, say they wouldn't trade it for anything that follows.
"Living the dream" is an understatement.
