"What makes life difficult is that the process of confronting and solving problems is a painful one. Problems, depending upon their nature, evoke in us frustration or grief or fear or anxiety or anguish or despair. These are uncomfortable feelings, often very uncomfortable, often as painful as any kind of physical pain, sometimes equaling the very worst kind of physical pain. Indeed, it is because of the pain that events or conflicts engender that we call them problems. And since life poses an endless series of problems, life is always difficult and is full of pain as well as joy.
Yet it is in this whole process of meeting and solving problems that life has its meaning."
