I've noticed that people who have never worked with steel have trouble seeing this—that the motorcycle is primarily a mental phenomenon. They associate metal with given shapes—pipes, rods, girders, tools, parts—all of them fixed and inviolable, and think of it as primarily physical. But a person who does machining or foundry work or forge work or welding sees "steel" as having no shape at all. Steel can be any shape you want if you are skilled enough, and any shape but the one you want if you are not.

That's all the motorcycle is, a system of concepts worked out in steel. There's no part in it, no shape in it, that is not out of someone's mind

A single thought begins to grow in his mind, extracted from something he read in the dialogue Phædrus. "And what is written well and what is written badly—need we ask Lysias, or any other poet or orator, who ever wrote or will write either a political or any other work, in metre or out of metre, poet or prose writer, to teach us this?"
What is good, Phædrus, and what is not good—need we ask anyone to tell us these things?

Poincaré wrote, "If a phenomenon admits of a complete mechanical explanation it will admit of an infinity of others which will account equally well for all the peculiarities disclosed by experiment." This was the statement made by Phædrus in the laboratory; it raised the question that failed him out of school.

"Anxiety, the next gumption trap, is sort of the opposite of ego. You're so sure you'll do everything wrong you're afraid to do anything at all. Often this, rather than "laziness" is the real reason you find it hard to get started"
