I will never be in a position to understand this internal restructuring you are doing. 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. It is healthy to understand that we cannot do everything the way we used to.
Your situation is a bit different where you are somehow coerced by situation to adapt. Having said that, you may have had to do the same restructuring irrespective of that :)
So, be kind to yourself. Let things go relax a bit. You have so many other things to provide value with your experience and muscle memory. My comment is based on the information you have shared and it is definitely limited.
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.
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.
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 :)
