Creation is a sustained period of bliss, even though the subject can still be very sad. Because there's the triumph of coming through and understanding that you have, and that you did it the way only you could do it. You didn't do it the way somebody told you to do it. You did it just the way you had to do it, and that is what makes us us.
Softness triumphs over hardness, feebleness over strength. What is more malleable is always superior over that which is immoveable. This is the principle of controlling things by going along with them, of mastery through adaptation.
And have you never known the pleasure and triumph of a lucky guess? I pity you. I thought you cleverer; for depend upon it, a lucky guess is never merely luck. There is always some talent in it.
