I would rather sustain the penalties resulting from over-conservatism than face the consequences of error, perhaps with permanent capital loss, resulting from the adoption of "New Era" philosophy where trees really do grow to the sky.
Stop turning on your emotional television to watch the same program over & over again, the one that shows how much you suffered from a certain loss: that is only poisoning you, nothing else.
Insignificant, is the loss of relatives, wealth and fame; The loss of wisdom is the greatest loss. Insignificant, is the increase of relatives, wealth and fame; The increase of wisdom is the highest gain. Therefore, you should train yourselves thus: "We will grow in the increase of wisdom" Thus you should train yourselves.
We build but to tear down. Most of our work and resource is squandered. Our onward march is marked by devastation. Everywhere there is an appalling loss of time, effort and life. A cheerless view, but true.
