Tao Te Ching: Chapter 3

No favourites, no rivalry.

No treasures, no thievery.

No objects of passion, no loss of contentment.

So keep the mind empty and keep the heart full.

Weaken ambition and strengthen the bones.

Know nothing, want nothing, do nothing,

and things will look after themselves.

Setting our hearts on this path, everything we do becomes our magnum opus, and through whole-hearted refinement we make it a monument worthy of spending a life on.
