The harsh, useful things of the world, from pulling teeth to digging potatoes, are best done by men who are as starkly sober as so many convicts in the death-house, but the lovely and useless things, the charming and exhilarating things, are best done by men with, as the phrase is, a few sheets in the wind.
Sometimes it is not wise to make a second plan; it diminishes the power of the first plan! In risky paths, make only one plan; this will increase the possibility of success! On the edge of a precipice, if your second plan is a parachute on your back, your possibility of falling will increase! When you have nothing to trust, you will be safer, because you have no right to make any mistake!
