Advice, Laozi, Dao De Jing

善行無轍迹，善言無瑕讁；善數不用籌策；善閉無關楗而不可開，善結無繩約而不可解。

- 老子, 道德經

The skilful traveller leaves no traces of his wheels or footsteps; the skilful speaker says nothing that can be found fault with or blamed; the skilful reckoner uses no tallies; the skilful closer needs no bolts or bars, while to open what he has shut will be impossible; the skilful binder uses no strings or knots, while to unloose what he has bound will be impossible.

- Laozi, Dao De Jing
