Whats the purpose of living life if all we do is work, eat, have , and die?

I agree completely. Until the time someone graduates high-school, the whole of that person's life is geared toward "success". And then what? Exactly. I recommend finding something that you enjoy so much you would rather die than live without it, and pursue it. For me, I love being in the outdoors, and mixed-martial arts. Try and find something like that.
