What is are a waste of time really. If what you are doing with your free time makes you happy, that’s all that’s needed. Life is too short not too enjoy it as much as possible. If that means watching looney toons and drinking beer, awesome sounds like fun! Sitting in a hot bath/tub reading comics and selling champagne, that seems like fun too! Regretting what you enjoyed in the moment because it wasn’t something more profound isn’t healthy. Enjoy your life however you want to enjoy it.
