I thought this as well, then found myself in the situation of not needing to work and found that, after some period of hedonism, it became quite empty. I think in the past it was easier for more people to experience this. We had less 'stuff' but much larger families and lived in generally more social systems. Those mitigate a lot of the coercive extrinsic pressures to work. And I think this is why philosophy, especially personal philosophy trending towards self betterment, was so much more prevalent in the past.

Aspire to at least leave the world better than you found it, so it is a little better when you are gone.
