What remains at the end?

That feeling of wanting to get the better one, a more expensive one, the best, the top of the line, of having more and more and more...I have forgotten what I really wanted, worst, I have lost myself too.

Ecclesiastes 1:2; 2:21-23

"Vanity of Vanities" For so it is that a man who has labored wisefully, skillfully and successfully must leave what is his own to someone who has not toiled for it at all. This, too, is vanity and great injustice; for what does he gain for all the toil and strain that he has undergone under the sun? What comes from all his laborious days, his cares of office his restless nights? This, too, is vanity.
