I on the other hand, at 40 with family&child, I don’t have the same patience for just anything that comes my way. Only if something sparks my interest I manage a way to make some progress. Last year I begun a slow journey into lisp/scheme and found the same flame i had when i was a junior. With other mundane things I’ll most likely get a shallow depth of knowledge to the level needed to get my work done and if needed i do some deep dives. I used to go in depth at first but lately i found that the return on investment wasn’t too appealing.
I hope to still have the acument to learn later on in life when I have more time and fewer responsibilities
