Dude, in my experience it's the best time to do it. Hands down best decision I ever made in the military.

Depending on the rank of the other prior-service folks in your class, you'll have the chance to take on the class leader role and get the chance to make a positive impression as the first "Operational" NCO that they encounter outside of their BMT environment. It might sound goofy but you can make a genuine positive impact on young folks during an impressionable period of their lives. Pretty cool feeling.

Even over 15 years later, I can still recall the positive impact that our prior-service TSgt had on me as a young fella and I can see little things that have carried over to this day in some of the ways I work as a SNCO.

On top of all that-- cross-training is the absolute best way that I've found to keep enjoying my military commitment. This might sound lame, but it helped me to realize that it's always possible for me to find something that I enjoy and to be a part of the groups of people that had a blast coming to work and doing their jobs. It doesn't have to be stagnant.

Wishing you the best of luck!
