"The hunter is the alert man. But this itself-life as complete alertness-is the attitude in which the animal exists in the jungle."

Next Quote

Cultivate the habit of thinking ahead, and of anticipating the necessary and immediate consequences of all your actions.... Likewise in your pleasures, ask yourself what such and such an amusement leads to, as it is essential to have an objective in everything you do. Any pastime that contributes nothing to bodily strength or to mental alertness is a totally ridiculous, not to say, idiotic, pleasure.

— Lord Chesterfield
