That depends. If your end goal is merely happiness then no, as long as you can still find a way to motivate yourself to eat, get enough physical activity to stay alive and provide yourself at least basic shelter and essentials.
If your end goal isn't happiness but fulfillment or meaning or something else that will also trigger happiness then there's an excellent argument against doing that, since it will eventually become all you do or care about.
