Don't part with your illusions. When they are gone you may still exist, but you have ceased to live. To live a fulfilled life, we need to keep creating the "what is next", of our lives. Without dreams and goals there is no living, only merely existing, and that is not why we are here.
We are always more anxious to be distinguished for a talent which we do not possess, than to be praised for the fifteen which we do possess. Sometimes we are too close to the scene, to see clearly. We "know" ourselves so well that we cannot see how we are perceived by others. Our opinion of ourselves is only "one" opinion and it may not be the truth.
When I was fourteen, my father was so ignorant I could hardly stand to have him around. When I got to be twenty-one, I was astonished at how much he had learned in seven years. See what happens when you "know it all", at any stage of life? Farther down the track you may see clearly how certain personal opinions, held onto too tightly, could be fogging up the view, and providing incorrect insight. Prosperity is the best protector of principle.
