I believe the principle fault of the majority of writers and artists is having neither the will nor the courage to break with their successes, failing to seek new paths and give birth to new ideas. Most of them produce them twice, three, even four times. They have neither the courage nor the temerity to leave what is certain for what is uncertain. There is, however, no greater pleasure than going into the depth of oneself, setting one's whole being in motion and seeking for new and hidden treasures. What a joy to find something new in oneself, something that surprises even ourselves, filling us with warmth.
