This is a short poem “YOUR BEST” from Barbara Vance’s book “Suzie Bitner was Afraid of the Drain”. I like it so much because it kind, friendly and very optimistic.

If you always try your best

Then you’ll never have to wonder

About what you could have done

If you’d summoned all your thunder

And if your best was not as good

As you hoped it would be,

You still could say,

“I gave today all that I had in me.”
