flexagonDear internet,
It's Thursday, and so I'm feeling a little lonely. So far this business trip has had two fantastically redeeming virtues though, not counting the sun and warmth of California:
1) I cleaned out my Amazon wish list on Mon/Tues and I'm AMAZED how good it feels to have done so. I bought about nine things (almost all used) and deleted a few more than that, and now I have four things remaining on the list. On my way to me in the mail: very random selection of used children's books, science fiction, the Sims 2 official game guide, a cookbook, a CD, recreational mathematics. :)
2) Bought and devoured a book called The Talent Code and I thought it kind of rocked. In subject matter, it's about how skills are learned... and that means it's largely about brains (BRAAAAINS) and about how neural pathways are enforced via wrappings of myelin around the nerve fiber. In authorial tone, it's entertaining and easy on the ear.
Most inspirational point (to me): myelin doesn't care who you are--it cares what you do. When a neural circuit fires, oligodendrocytes and other supporter cells sense it and reach out to wrap that circuit with myelin (which acts as electrical insulation). Signals can travel down a well-myelinated circuit up to 200x faster than down a non-myelinated circuit, and myelin can even alter the speed of a signal so that (for instance) two signals arrive in the same place at the same time. [No wonder it feels "natural" to do something you've done a million times before. It's not false modesty on your part, or getting used to how something feels over time, it's the actual perception of using a part of your brain that's become wired for broadband signal transmission.]
So skills are formed by firing the circuit, thoughtfully, attentively. Fine tuning, adjusting, getting out there and firing it and firing it. Another quote I liked very much: Struggle is not an option: it's a biological requirement. Myelin doesn't know who you are or why you're doing something, but it rewards attempted precision with more precision and more ease.
And this theory makes so much sense: skills are generally formed slowly instead of quickly because, though neurons fire fast, wrapping the suckers is slow. It may take days or weeks for a single section of myelin to curl up tight into the 40-50 wraps around an axon that it's capable of. Myelinating a big circuit takes a lot of time and dedication. You have to care enough to keep firing it for all that time. Becoming a world-class anything takes around 10,000 hours of practice, as documented in many books before this.
So, I knew some of that, but the book gave me more to think about. It talks about how to practice effectively, and that's useful. It also discusses "talent hotbeds", the places where huge blooms of talent seem to arise, and coaching techniques, and the things that trigger different people to have the energy and drive and passion it takes to myelinate like crazy. And, all somewhat speculative neuroscience aside, that is the chapter that taught me something so huge about myself that I don't want to blog it. I want to know my own triggers... I don't necessarily want the world to know them.
P.S. Miss you, kitty.
