Is this world worth living for?

Everyone says that you can only live once, so work hard and use 100 percent of your time to have a great life. But that doesn't make any sense...

Why should we do our best to achieve something that, eventually, we're going to lose when we die?

I'm not trying to be pessimistic, but when I see people on the street, I notice they're working hard just to have a better life—one where they'll eventually be buried with everything they’ve worked for.

I know some will say that life is all about experiencing things, but every time I hear that from someone, they can't provide a compelling reason why it's enough.
