Tao Te Ching 24

He who stands on tiptoe is not steady.
He who strides cannot maintain the pace.
He who makes a show is not enlightened.
He who is self-righteous is not respected.
He who boasts achieves nothing.
He who brags will not endure.
According to followers of the Tao, "These are extra food and unnecessary luggage."
They do not bring happiness.
Therefore followers of the Tao avoid them.

Proportion

You can't keep standing on tiptoe
or walk in leaps and bounds.
You can't shine by showing off
or get ahead by pushing.
Self-satisfied people do no good,
self-promoters never grow up.

Such stuff is to the Tao
as garbage is to food
or a tumor to the body,
hateful.
The follower of the Way
avoids it.

24. Indulgence

Straighten yourself and you will not stand steady;
Display yourself and you will not be clearly seen;
Justify yourself and you will not be respected;
Promote yourself and you will not be believed;
Pride yourself and you will not endure.

These behaviours are wasteful, indulgent,
And so they attract disfavour;
Harmony avoids them.
