Kourosh Dini really has the right approach for teaching habits/tools:

Not coincidentally, my books and courses all begin small and gently:

  • Creating Flow with OmniFocus begins with a single repeating task. The idea is to begin and grow at the reader’s natural pace.

  • Waves of Focus begins with the Anchor Technique, a simple pen and paper method of managing the whims of the Now. Everything starts with where you are Now.

  • Taking Smart Notes with DEVONthink guides you to building even a huge database, but it starts with a single note.
