British sculptor Sir Jacob Epstein was once visited in his studio by the eminent author and fellow Briton, George Bernard Shaw. The visitor noticed a huge block of stone standing in one corner and asked what it was for.
“I dont know yet. Im still making plans.”
Shaw was astounded. “You mean you plan your work. Why, I change my mind several times a day!”
“Thats all very well with a four-ounce manuscript,” replied the sculptor, “but not with a four-ton block.”
