Reading over a letter you wrote the night before is an act of denying yourself. When you read it over, you’re bound to find at least one or two sentences you want to erase, like a mistake you made in the past. I don’t think you need to be ashamed of them, since they’re symptoms that occurred because you were too true to your feelings, or because you were full of courage. If we don’t allow ourselves to have courage at night, at least, we’ll have to live as cowards all our lives.
