Suppose you wanted to become tougher and suppose too that you believed that you could only do so by training. Suppose, thirdly, that such training would consist of “tests of characters”–events that, putting pressure on you, come your way and require your right response–and of contests.

Set aside tests of character for now. Contests would range from easier to harder. What would be the logical order of contests?
