Earlier quoted context omitted.
I personally don’t find TV a time waster. If you enjoy it, as I do, then do it, guilt-free. However if you find yourself addicted ie you want to do other things but you keep getting “sucked in” then by all means stop - it will have a noticeably positive impact.
I wasn't feeling like TV directly prevented me from doing anything else, but it still felt like a big relief when I finally sold my TV. It didn't feel like it was stealing any of my time, still, my daily activities at home changed to something that feels much more productive and healthy. I read more, and spend more time with my personal projects. TV is sneaky, you don't realize how much time of your life it consumes.
(Not in any way criticising you - just the community here often appears obsessed with maximising personal output and I think jeez just relax sometimes guys!!)
