In my opinion, a lot of things people do are a "waste of time". A lot of things people do for fun wont actually help you in life, but that doesn't mean you shouldn't do any of it. Take watching TV for example. Almost everybody does it, but does it actually help you with anything? No. But does that mean nobody should do it? Almost everything people do for fun the internet will be useless in real life, but as long as your not doing these kind of things all day without doing anything else, none of it is really a "waste of time".
