For many, Monday is a day that starts a cycle with some hope of completing it by Friday. But as someone once said, “Only Robinson Crusoe had everything done by Friday“. I often find taking unexpected breaks to be just as productive as plowing ahead. It’s pretty easy to spew out quotes about positive attitude and not quitting:

Your attitude, not your aptitude, will determine your altitude.
-Zig Ziglar

Success comes in cans, failure in can’ts.
-Unknown

But sometimes, another approach is completely acceptable:

If at first you don’t succeed, try, try again. Then quit. There’s no use being a damn fool about it.
-W. C. Fields

Take rest; a field that has rested gives a bountiful crop.
-Ovid

Perhaps the main thing is to not dwell on it:

Some of us think holding on makes us strong, but sometimes it is letting go.
-Herman Hesse

One problem with gazing too frequently into the past is that we may turn around to find the future has run out on us.
-Michael Cibenko

And make a decision when all the facts are in. Or is that when they’re NOT all in? I forget.

A decision is the action an executive must take when he has information so incomplete that the answer does not suggest itself.
-Arthur William Radford
