I assume we are of similar age bracket and I can certainly tell, based on my experience, that at one point in professional career we do need to go back and resketch the parameters
I think it is healthy to do this in small ways regularly, but it is difficult when it is all at once and by circumstance, made even harder.
Your situation is a bit different where you are somehow coerced by situation to adapt.
Yes, but I think many of us who aren't consistently improving and pivoting will be "coerced" at some point, because demanded skills change, industries come and go. If we don't have a process to develop and adapt, we will get left behind eventually.
You have so many other things to provide value with your experience and muscle memory.
I wish I had a little more muscle memory to fall on! :D
Yes, that's what I was referring to. I am already thinking of how I should update on the policy work to capture what is happening around the world in terms of new trending skills that can make me relevant.
You have more muscle memory than you can realize. It will get activated once you start mapping your mental strength :)
