"Education isn't something you can finish"
One thing is certain - we never stop learning new information as we go through life. That is why I think that it is important to always seek and acquire new knowledge, new skills and experiences through self-education, personal development, training, etc. Even the information that we do know today, may change, may evolve, may expand with new facts, ideas, theories. Therefore, don't assume that what we know is all that there is to know, because you will be surprised to learn how far such thought is from the truth. Don't you agree?
