The most difficult aspect of personality development is detaching oneself from the bonds that are formed as a result of the positive impact of certain discoveries. There comes a time when, having already fulfilled their uplifting function, they cease to contribute. It is then necessary to let go of the habit that arose from them; it is necessary to replace it with one more in line with one’s current state. This cannot be done without some discomfort; failing to do so, however, leads to stagnation.
