Time for me to get philosophical. I would say that time you "waste" doing something that gives you happiness and fulfillment is pretty far from time wasted. Life is short and can often feel pointless in some sense so if your lucky enough to be comfortable try your best to enjoy it. As someone who is not religious I am not convinced there is much else to be had. For sure don't overindulge in short term hedonic pleasures at the expense of long term fulfillment or the happiness of others. I feel like we all know deep down in aggregate this is far from an optimal life but I think we should distinguish externally or societally "useless" from useless.
To clarify my last comment. I think a lot of us recognize that a life where we just in more basic terms "do what is fun or makes me happy" is paradoxically actually in aggregate not the happiest life.
