Diligent, and intelligent. Diligence quickly accomplishes what the intelligence has well thought out. Haste is the passion of fools, and as they know not the difficulties, they work without heed: wiser men, on the other hand, are likely to fail from over-caution; for of reflection is bred delay: and so their hesitation in acting loses them the fruits of their good judgment. Promptitude is the mother of fortune. He does much who leaves nothing for tomorrow. A magnificent motto: to make haste slowly.
