“One today is worth two tomorrows”

“Never leave till tomorrow that which you can do today.”

“Don't put off until tomorrow what you can do today.”

“Work while it is called today for you know not how much you may be hindered tomorrow.”

“Your net worth to theworld is usually determined by whatremains after your bad habits aresubtracted from your good ones”

“Either write something worth reading or do something worth writing.”

“If you would not be forgotten, as soon as you are dead and rotten, either write things worth reading, or do things worth writing.”
