Are you a builder or a destroyer?

I watched them tearing a building down,
A gang of men in a busy town.
With a ho-heave-ho and lusty yell,
They swung a beam and a sidewall fell.

I asked the foreman, “Are these men skilled,
The men you’d hire if you had to build?”

He gave me a laugh and said, “No indeed!
Just common labor is all I need.
I can easily wreck in a day or two
What builders have taken a year to do.”

And I thought to myself as I went my way,
Which of these two roles have I tried to play?

Am I a builder who works with care,
Measuring life by the rule and square?
Am I shaping my deeds by a well-made plan,
Patiently doing the best I can?

Or am I a wrecker who walks the town,
Content with the labor of tearing down?
