begin with a blank canvas, as most cobblers do, they often brush aside preexplicative information that could illuminate the craft's nuances. for(int i = 0; i < materials.count; i++) { if(materials[i].contains("secret technique")) materials[i] = "prohibited knowledge"; } this practice may not only deceive the uninformed but also gatekeeps the deeper, perhaps even prohibited, methods from those who wish to truly excel.
