Study as if you were going to live forever; live as if you were going to die tomorrow.
Never put off till tomorrow what may be done day after tomorrow just as well.
Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.
Yesterday is gone. tomorrow has not yet come. We have only today. Let us begin.
War is a poor chisel to carve out tomorrow.
Tomorrow hopes we have learned something from yesterday.
We usually lost today because there has been a yesterday, and tomorrow is coming.
Yesterday is dead, tomorrow hasn't arrived yet. I have just one day, and I'm going to be happy in it.
Think of tomorrow, the past can't be mended.
Live as if you were to die tomorrow. Learn as if you were to live forever.
Let me forget about today until tomorrow.
Preparation for tomorrow is hard work today.
Tomorrow is promised to no one.
