The thing about joy is it comes in waves, like everything . The same way awful things don't last forever, neither do the good things. It's all a series of ebbs and flows and waves that we learn to ride better with time. Finding things that bring you joy help to prolong those good moments. They also help you to appreciate the good moments that much more, because we know they're fleeting and it's all a part of this weird human experience we've been chosen to endure.
