You don't remind me of this, but this topic (career change, challenges) does. Navy bud of mine is having a rough time getting hired in 121 land. Chatting on phone, he's kinda getting desperate now that he has retired from Uncle Sam, and is worried about putting food on the table. I told him "dude, there are literally a million awesome things you could go get paid to do right now......like 3 of them involve flying airliners (or even flying). Don't stress". And fortunately for you, you've got a mature career now. Sometimes the grass isn't greener.
