Most people trying to fix a motivation slump also have a job, a family, or both, so the plan has to fit around real constraints, not an ideal version of the day.
That means picking one cue that already exists in your day - after you make coffee, after you sit down at your desk - rather than inventing a new block of time you don't have.
This is where Lasting Change fits in: the book is built around your actual goal and your actual lifestyle, with habit strategies suited to the time and energy you really have, not a generic routine lifted from somewhere else.
The companion app then keeps the visible progress part simple, so tracking does not become another task competing for the energy you are trying to rebuild.
