If you get in the lull of another job, then you must enjoy that other job, so what's the problem?
I think you need to slow down and relax a bit. There's nothing wrong with reaching a regional after 25, and you'll enjoy it a lot more if you stop and smell the roses along the way. Besides, what happens if you don't get a job right out of the RAA? You'll have spent all that money and not be marketable at all with only 500 hours. Will you come away with any CFI certificates or not?
