Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true.
I am beginning to see that all my troubles have their root in a habitual and absolute dependence upon my personal prestige, security, and romantic attachment. When these things go wrong, there is depression. Now this absolute dependence upon people and situations for emotional security is, I think, the immense and devastating fallacy that makes us miserable. This craving for such dependencies, this utter dependence upon people and situations, can only lead to conflict. Both on the surface and at depth. We are making demands on circumstances and people that are bound to fail us. The only safe and sure channel of absolute dependence is upon God himself.
Do not depend on the hope of results. You may have to face the fact that your work will be apparently worthless and even achieve no result at all, if not perhaps results opposite to what you expect. As you get used to this idea, you start more and more to concentrate not on the results, but on the value, the rightness, the truth of the work itself. You gradually struggle less and less for an idea and more and more for specific people. In the end, it is the reality of personal relationship that saves everything.
