A paradox

Quite unexpectedly I've found a paradox of my life in Vern McLellan's book Shredded Wit. It goes like this:

Bite off more than you can chew, then chew it.

Plan more than you can do, then do it.

Point your arrow at a star, take your aim, and there you are.

Arrange more time than you can spare, then spare it.

Take on more than you can bear, then bear it.

Plan your castle in the air, then build a ship to take you there.

A paradox - absurd, unbelievable, but true.
