Good morning,,
One of the things that we should appreciate most in life, is knowledge, is what will allow us to develop as individuals. A person without knowledge, hardly, could have opportunities that allow him to grow, but, as you mention, if the knowledge we have, we do not apply the adequate concentration and, the full attention, so that what we know, we can use it properly, Hardly that knowledge will make us useful.
A life without knowledge is empty, it is very important to learn, learn and keep learning, that will give us the tools to develop, but we must know how to apply them in order to succeed in life
