The easiest way to thrive as an outlier is to avoid being one. At least among your most treasured peers. Surround yourself with people in at least as much of a hurry, at least as inquisitive, at least as focused as you are.
"Be grateful to everyone" is about making peace with the aspects of ourselves that we have rejected. . . If we were to make a list of people we don't like - people we find obnoxious, threatening, or worthy of contempt - we would discover much about those aspects of ourselves that we can't face. . . other people trigger the karma that we haven't worked out.
