Tao Te Ching, Verse #3

不尚贤，使民不争。
不贵难得之货，使民不为盗。
不见可欲，使民心不乱。
是以圣人之治，虚其心，实其腹，弱其志，强其骨；
常使民无知无欲，
使夫智者不敢为也。
为无为，则无不治。

Not to idolize persons' intellect and ability, there will be no competition.
Not to treasure hard to get items, there will be no stealing.
Not to lure with desirables, there will not be disturbance to peace in mind.
Therefore, sage manages by encouraging people to be humble, to focus their efforts on working hard to put food in their stomachs, to reduce their ambitions and to strengthen their health. He often teaches people to get rid of worries by choosing not to know and to avoid to have desires. So the intelligent people would not dare to show off and cause chaos in society. Because there is no competition, no stealing and no disturbance to peace in mind, there will be peace.

Philosophically, I learned:

1. Not to be arrogant because you are intelligent. Not to think you are smarter than other people.

2. Minimize desires to reduce temptation to do bad things.
