While I think everyone can eventually learn, I know a few smart people for whom it just doesn't click. Like, people who are great at math but get confused by simple concepts like variables and pointers. I know for me there are some topics that I just don't get myself and unable to make a first move. Like woodworking, how would I even approach something like building a chair? I have no idea even though I've read and watched a few guides, just got a myriad of dumb questions instead.
