Cleverness and wisdom are different. Many people are clever, but very few can possess wisdom. There is big difference in it.
The principle of clever people is to take advantage from others, and protect their own benefit very seriously. They only aim at their today’s benefit, neglecting future’s benefit.
But, the people of wisdom have a far-sighted plan, not confining to today’s benefit. To make simple, great people are of wisdom group and clever people are of short-sighted.
When we communicate with people who mostly are clever ones, we must be beware that they may take advantage from us. Clever persons will only make friendship with you if you can give them benefit of any kind. They do not wish to be friend with you if you cannot help them in any circumstance.
Some people can make instant friendship and build a close relationship. It is because they have something in common. If two persons like music very much, it is easy for them to be in close friendship quickly.
But, for most of us, it is better to build friendship with any one slowly and shallowly. A wrong friendship may bring us troubles and even disasters. We had better to have friends of wisdom from whom we can learn many things about our life.
