But if a grown man's character is developing from day to day (as it is), if nine-tenths of the development is due to unconscious action and one-tenth to conscious action, and if the one-tenth conscious is the most satisfactory part of the total result; why, in the name of common sense, henceforward, should not nine-tenths, instead of one-tenth, be due to conscious action? What is there to prevent this agreeable consummation? There is nothing whatever to prevent it--except insubordination on the part of the brain. And insubordination of the brain can be cured, as I have previously shown. When I see men unhappy and inefficient in the craft of _living_, from sheer, crass inattention to their own development; when I see misshapen men building up businesses and empires, and never stopping to build up themselves; when I see dreary men expending precisely the same energy on teaching a dog to walk on its hind-legs as would brighten the whole colour of their own lives, I feel as if I wanted to give up the ghost, so ridiculous, so fatuous does the spectacle seem! But, of course, I do not give up the ghost. The paroxysm passes. Only I really must cry out: 'Can't you see what you're missing? Can't you see that you're missing the most interesting thing on earth, far more interesting than businesses, empires, and dogs? Doesn't it strike you how clumsy and short-sighted you are--working always with an inferior machine when you might have a smooth-gliding perfection? Doesn't it strike you how badly you are treating yourself?'
