People's troubles come from human desires, people's desires come from people's abilities.

Human's annoyance comes from the human desire, the human desire comes from the human ability.

The stronger the ability, the greater the desire, the greater the desire, the more trouble.

Therefore, the desire to one point less, then worry less one point, happiness will be one point more.

Perhaps as "Zhang Lie" in the said, "the skillful labor and knowledge of the worry, the incompetent are not asked." If you swim with your stomach, you will not be a boat, but a person who does not swim.

There is also a poem:

Armored General Night Crossing,

The courtiers were just before dawn cold in the leak.

Mountain Temple Day monks not up,

It's better to be idle than to count fame.

That's probably what it means.

People's troubles come from human desires, people's desires come from people's abilities.
