There is an old story about Pablo Picasso. Lady comes up to him, asks for an autograph. He does it and she then asks if he would do a little doodle on the paper. He does it and as he hands the doodle/autograph back, he says $50K please. The lady is indignant. How dare you charge me $50K for a doodle that took you a minute to make, she said. Picasso replied, I'm charging you the 50 years it took to give me the ability to make that doodle.
The idea you can take a class and master a craft is asinine. Anyone to suggest it has never made a thing in their life. Do yo need the 10,000 hours as the lore says? Probably not. But 40 hours in a class ain't gonna cut it at all. I believe an apprenticeship is the best means of learning a trade, beats school hands down.
I will also say I have never met Sachs in person. He may be the greatest person in person for all I know. On the other hand I also know what he writes is just BS. This isn't the first dumb **** thing he wrote, I'm betting it ain't the last.
Now, I need to to get my princess ass as sensitive as Doc's so I can feel that pea.
