different than someone who wants to produce as much personal change as possible in 3 days.

Sure. But the "we must make big changes in three days" model is itself a choice, which may turn out to be suboptimal for making long-term life changes.

Exercises should reinforce each other instead of being completely distinct.

As I understand it, it's generally true of skills training that if there are multiple independent aspects to a skill (say, precision and power in a golf swing), the skill improves faster if I train those aspects separately.
