Knowledge is not everything, it must be put into practice.
Intelligence consists not only in knowledge, but also in the ability to apply knowledge in practice - Aristotle.
I believe that many of us do not enjoy great knowledge of wisdom but the little we have we have a duty to put it into practice, since the wise person is known because he lives a life of integrity or at least putting into practice much of what you say.
Congruence:
This word may be small but it boasts much, and it has boast accomplished, for it means that our words and should go according to our rights and our deeds should go according to our words.
How many of us have known people who talk a lot but do little, when we have known people who manifest great knowledge and great wisdom but when we see the way they live the way they love the way they work we realize that they do not seem to have much knowledge, what is it about having wisdom because wisdom is that knowledge that is put into practice, and for that we need to be intelligence and intelligence is acquired by understanding, learning, reasoning and studying.
I think many more of us would apply the knowledge we have, we would make much more changes around us than we imagine, the case that nations and cities would be different, and say of families and homes.
