The author explains how predefined rules and processes can replace the need for constant motivation.

He argues that abstract goals like 'study more' are hard to achieve, but concrete processes make them automatic, citing Agile and Scrum as examples from software development.
Instead of needing to find motivation and act on it, you can cut out the tricky bit, and just be left with an action.
