TA, you've already started threads on how watching football is a waste of time, and we've already gone over that what can be considered a "waste of time" is determined by the individual.
I had a good time watching the game and hanging out with friends last night. Reading a book and gathering knowledge about something I will never be able to put to practical use would've been a waste of time for me.
You enjoy reading and educating yourself on topics that will never benefit you in any way shape or form other than giving you the pleasure of being smarter than your next door neighbor and a few people on getbig. I see that as an incredible waste of time.
Many people would see your time spent of getbig as an incredible waste, but you clearly don't. It's all based on the individual.
