This is basically the approach I learned from HTDP, and it's helped me greatly for tackling some tougher problems. Basically you make a "wish list of" the functions/steps you'd like to be able to do, and then as you work on writing those functions in your wish list, you do the same thing again, going down and down until you hit the bottom and do concrete action with primitives or whatever. It's really cool to see how this can work by composing pure functions and types. https://htdp.org https://htdp.org
