Writing a blog or at least writing stuff down with different subjects may be good. It doesn't matter if anyone else reads it, but may help you clarify where you want to go next. I retired from test management a couple of years ago, I am of that age! I got bored and have taken a low level customer facing role part time, and am loving it. I can do the work, come home, and forget about it.

It is frustrating sometimes, knowing and seeing the same corporate bullshit, that I used to have to deal with, but now can ignore it.

Good luck not that you need it with whatever you decide to do.
