It’s often confusing (“scary”?) to start learning something complex. In reality, Tinderbox is not complex if you take it slow. I like this recent thought on a different, far more complex subject (biology):
Enormous subjects are best approached in thin, deep slices. I discovered this when first learning how to program. The textbooks never worked; it all only started to click when I started to do little projects for myself. The project wasn’t just motivation but an organizing principle, a magnet to arrange the random iron filings I picked up along the way. I’d care to learn about some abstract concept, like “memoization,” because I needed it to solve my problem; and these concepts would lose their abstractness in the light of my example. jsomers.net | I should have loved biology
The common - and I think best - advice is to invent a note making project for yourself, ask yourself (and/or here) “how best to start this?” Then start. And continue.
