It is the condition of our present state to see more than we can attain; the exactest vigilance and caution can never maintain a single day of unmingled innocence.
Samuel JohnsonAn Italian philosopher said that "time was his estate"; an estate indeed which will produce nothing without cultivation, but will always abundantly repay the labors of industry, and generally satisfy the most extensive desires, if no part of it be suffered to lie in waste by negligence, to be overrun with noxious plants, or laid out for show rather than for use.
Samuel Johnson
