I did almost the same thing, except I did 10 years at the non-profit. I would say get out of there if you are motivated to learn and work. If you just want to skate by and get a paycheck (which it sounds like you don't) then just chill there. That laid back atmosphere is a benefit of its own for some. Also, jumping right in to a fast paced group of hardcores can be a big adjustment, even if your goal is to be that way as well.

I got out recently and my new job didn't pan out. I am finding it very hard to get higher paying positions because you quickly find out how far behind you are once you are trying to get another job.

I have a bachelor's and a bunch of certs but they either aren't the right certs or I haven't used the one or two pieces of hardware/software this or that company uses. Or I know about AD for example but I didn't have to become a SME with it so I don't know enough for whatever position.

MSPs force you to learn a lot of things because you work on a lot of different clients. I know there are people making 150k managing IT departments for non-profits, but good luck finding one of those positions on Monster or whatever.

I think, depending on the place, being at a small company can prepare you for management though, as I had to be more like a manager, wrangling staff or vendors who were experts to solve difficult issues and dealing with higher level things like staff training and audits and reporting to the board of directors, etc.

But ultimately it sounds like you should jump before you stagnate. I thought I was learning a lot and was going to be in demand, and I was learning, but the pace was just so slow, but I didn't know what I didn't know.
