How do you measure the worth of a man?

[Grinner]

People who spend all their time being introspective and bettering themselves are no better than those who spend all their time doing nothing. It is achievement that marks the value of a man. Build something or break something, but the magnitude of that change upon the world is what matters.

Inventing things could be seen as a way of bettering others or merely getting rich. Besides, it is true that leaving a legacy makes a much greater impact over time. On the other hand, it can be argued that mankind's inventions will be as ephemeral as mankind itself.

Edit:

I also have... a few other ways to figure out what we value.

Don't keep us in suspense now.
