Problem is, by the time you start to hear about rules, find out what somebody else says that they are, begin to subscribe to them, you might well find that you have thrown your chance of being you and not a rule-addicted clone of whichever master whose rule you have decided is the shining path to wisdom and serenity.
I wonder if Haskins followed rules, Avedon, Stern, Bailey, French, Sieff, Horvat, Moon, Watson, Demarchelier, Kane, Turner etc. etc. - you get the photo...
