Never, we know all friend @chbartist, always, people have the need to learn more and more, and the more we study, the more we learn.

Certainly, there are predisposed people, who because they are not interested in a topic, or think they know everything, they lose interest in continuing to learn from it, which leads them to miss the opportunity to continue deepening the subject, and continue acquiring knowledge. Knowledge is what makes us strong, looking to the future, and while, the more knowledge you have, the more possibilities you will have to successfully develop your activities or projects.
