It is not enough to stare up the steps, we must step up the stairs.
You can't be aware of everything. You'd fall down the stairs if you were aware of every intricate thing involved in going down stairs.
I came up stairs into the world, for I was born in a cellar.
Of all the ruinous and desolate places my uncle had ever beheld, this was the most so. It looked as if it had once been a large house of entertainment; but the roof had fallen in, in many places, and the stairs were steep, rugged, and broken. There was a huge fire-place in the room into which they walked, and the chimney was blackened with smoke; but no warm blaze lighted it up now. The white feathery dust of burnt wood was still strewed over the hearth, but the stove was cold, and all was dark and gloomy.
Never look backwards or you'll fall down the stairs.
Thou shall know by experience how salt the savor is of others' bread, and how sad a path it is to climb and descend another's stairs.
