If you have no problems with your current levels of creativity, focus, etc. is doing those things ("reading books, travel, learning a language or art") still superior to TV?
I wouldn't say superior. That would be snobby and ignorant, but I think it depends on "does it make you happy"? If you have to stop and think then maybe it doesn't. If not then great! Why change something that fulfills you. Doesn't matter what other say, or does it?
