That's definitely a smart move. I was happy to have served because it fundamentally changed me for the better. I was also happy when I got out. Years later, and for a time, I wished I had stayed in and reached retirement age while in the service.
Then it dawned on me that all the other fine things that I cherished about my life would have been entirely different; and so I mentally shrugged and let it go.
Life is like that, people are like that; and we are all wired different.
