From Hey World, Here I am! by Jean Little:

Today
Today I will not live up to my potential.
Today I will not relate well to my peer group.
Today I will not contribute in class.
I will not volunteer one thing.
Today I will not strive to do better.
Today I will not achieve or adjust or grow enriched or get involved.
I will not put up my hand even if the teacher is wrong and I can prove it.

Today I might eat the eraser off my pencil.
I'll look at clouds.
I'll be late,
I don't think I'll wash.

I need a rest.
