Be wise today; 'tis madness to defer. [ Young ]

Defer not till tomorrow to be wise,
Tomorrow's sun to thee may never rise. [ William Congreve ]

Defer no time, delays have dangerous ends. [ William Shakespeare ]

Be wise to-day! 'tis madness to defer;
Next day, the fatal precedent will plead;
Thus on, till wisdom is pushed out of life.
Procrastination is the thief of time. [ Edward Young ]

Cruelty is more cruel if we defer the pain. [ English Proverb, collected by George Herbert ]

Look not on pleasures as they come, but go.
Defer not the least virtue; life's poor span
Make not an ell by trifling in thy woe.
If thou do ill, the joy fades, not the pains;
If well, the pain doth fade, the joy remains. [ George Herbert ]

Whatever things injure your eye you are anxious to remove; but things which affect your mind you defer. [ Horace ]

Be wise today; 'tis madness to defer; Next day the fatal precedent will plead; Thus on, till wisdom is push'd out of life. [ Young ]

But since, however protracted, death will come. Why fondly study, with ingenious pains. To put it off? - To breathe a little longer is to defer our fate, but not to shun it. [ Hannah More ]

Receive with a thankful hand every hour that God may have granted you, and defer not the comforts of life to another year; that in whatever place you are, you may say you have lived agreeably. [ Horace ]

I shall pass through this world but once. Any good thing therefore that I can do, or any kindness that I can show to any human being, let me do it now. Let me not defer it or neglect it, for I shall not pass this way again. [ A. B. Hegeman ]

It unfortunately happens that no man believes that he is likely to die soon. So every one is much disposed to defer the consideration of what ought to be done on the supposition of such an emergency; and while nothing is so uncertain as human life, so nothing is so certain as our assurance that we shall survive most of our neighbors. [ Aughey ]
