OP here... I should say that I wrote this post rather late with a glass of wine in my hand and perhaps didn't use all the exact words to convey my point clearly. But let me address your points.

"Thinking too much" seems to have hit a button for you; sorry about that. I do think this is a pretty common thing: The Paradox of Choice. That's sort of what I am feeling as I know quite a few languages and frameworks, and it's difficult for me to stop diddling over "what should I use" and just write it.

I've spent my career creating things - I haven't created a language yet and to be honest I don't think I have the ability to do so. Not sure what that has to do with my point, but OK.
