Think to yourself that every day is your last; the hour to which you do not look forward will come as a welcome surprise.

In avoiding one vice fools rush into the opposite extreme.

While your client is watching for you at the front door, slip out at the back.

Don't just think, do.

One goes to the right, the other to the left; both are wrong, but in different directions.

In the midst of hopes and cares, of apprehensions and of disquietude, regard every day that dawns upon you as if it was to be your last; then super-added hours, to the enjoyment of which you had not looked forward, will prove an acceptable boon.

Youth is unduly busy with pampering the outer person.
