Yea, there's no intrinsic place for us to fit into the universe. In fact, the universe is quite random and entropy is everywhere. Just pursue what makes you happy.

Is there a purpose to playing video games all day? Nope. Am I having fun and enjoying life? Yup!

Just take everything with some moderation so you don't burn yourself out though. Frequent breaks here and there have recently become my lifesaver for not feeling exhausted all the time. Self care really is important.
