Programming has been this weird mix where I would see a simple problem. Say a fibonacci sequence. Something I could do in my sleep.
I would look at it. Understand that I can solve this in seconds. Then it would take me a week to muddle through it, badly.
So I know how to program just fine, but I somehow I can't actually do it. So it's been relearning things I think I know how to do.
The saving grace is people would often ask how to approach a difficult problem and I could still quickly figure out what the issue is, and what approach to take to resolve it. So I was very helpful to others, but I couldn't do the work I suggested.
Weird stuff.
