The most stupid (people) never ask a question. Because of that, there are, and there will never be exist, a stupid question.
Question asked is an indication that a brain is working. Beside of that, the original purpose of a question is to have an answer. If any question viewed and treated as its original purpose, as a stimulation to think of the answer, then how come a stupid question exist?
Smart is to have a knowledge about some thing. The more, the smarter. The most, the smartest. The smart will never be wise, unless she realized that the greatest wisdom of all is to know, that there are a lot of things that she doesn't know, and there are a lot of things to be learned yet.
Success achieved from an idea. Idea comes to answer a question. Idea refurnished to perfect by questions. The most success people is not the one who knows everything. The most success people is the one who ask everything, including the most silly like question, to her people/team mate.
Our glass will always have to be empty. If it is empty, we could fill it more and more and more...If we think that we know nothing, then we will always and strive to learn about something. If a glass is full, how can we fill it more? If we think that we are smart, we will not continue to learn anything in the future.
So, what do you think?
