The other day I happen to read an eighty-word passage about details. I found it prettily good.

One who wants to achieve great success should pay attentions to details. Sometimes it is the details in that determine our success, for it has a great impact on what we’re doing. We should form the habit of being careful, so a careful person rarely overlooks details. What’s more, we should learn to keep balance of quantity and quality. When facing with lots of work, the faster we do them, the more mistakes we usually make. In that case we are possible to neglect the details. So we should remember that quality comes first, without that quantity is of no importance.
