+consumes faster than Labor wears; while the used key is always bright,
+as Poor Richard says. But dost thou love Life, then do not squander
+Time, for that's the stuff Life is made of, as Poor Richard_ says. How

+_If Time be of all Things the most precious, wasting Time must be, as

+Time enough, always proves little enough_: Let us then up and be
+doing, and doing to the Purpose; so by Diligence shall we do more with
+less Perplexity. _Sloth makes all Things difficult, but Industry all
+easy_, as _Poor Richard_ says; and _He that riseth late must trot all
+Day, and shall scarce overtake his Business at Night; while Laziness
+travels so slowly, that Poverty soon overtakes him_, as we read in
+_Poor Richard_, who adds, _Drive thy Business, let not that drive
+thee_; and _Early to Bed, and early to rise, makes a Man healthy,
+wealthy, and wise._
