OP
There is joy in learning new stuff.
By choice, I will never stop learning. Well, I hope... I don't fear death or anything, but I do fear losing control of my faculties. So long as that's not a problem, I'll keep learning. It's habitual for me, probably because of all the years in an academic setting. I wouldn't have it any other way.
which is useful.
I could see that being useful. That's a pretty good tip. There's almost enough meat in this subject to create an article! LOL
