HAD I the heavens' embroidered cloths,
Enwrought with golden and silver light,
The blue and the dim and the dark cloths
Of night and light and the half-light,
I would spread the cloths under your feet:
But I, being poor, have only my dreams;
I have spread my dreams under your feet,
Tread softly because you tread on my dreams
W.B. Yeats
As Sir Ken noted in a related TED talk, everday our children spread their dreams beneath our feet. We should tread softly.
