Of course I can’t chop wood. I’m made of glass! Swing me against a hard tree, and I’ll shatter.
Imagine, though, that you were cutting down a paper tree. I could chop down a whole forest of paper trees with my fine edge.
You can turn anything around with your imagination. Hold to it, and you will never be shattered.
