There is no try. Do or do not.

The Little Blue Engine
by Shel Silverstein
The little blue engine looked up at the hill.
His light was weak, his whistle was shrill.
He was tired and small, and the hill was tall,
And his face blushed red as he softly said,
I think I can, I think I can, I think I can.

So he started up with a chug and a strain,
And he puffed and pulled with might and main.
And slowly he climbed, a foot at a time,
And his engine coughed as he whispered soft,
I think I can, I think I can, I think I can.

With a squeak and a creak and a toot and a sigh,
With an extra hope and an extra try,
He would not stop now he neared the top
And strong and proud he cried out loud,
I think I can, I think I can, I think I can!

He was almost there, when
CRASH! SMASH! BASH!
He slid down and mashed into engine hash
On the rocks below... which goes to show
If the track is tough and the hill is rough,
THINKING you can just aint enough!

Some interesting thoughts on self-efficacy as opposed to confidence. Enough reading to keep me going for a day or two.
