Steven Bartlett with James Clear
You do not rise to the level of your goals, but fall to the level of your systems. In Steven Bartlett with James Clear's habit-building and system-design playbook, the core message is that lasting change starts by fixing the inputs that shape your behavior day after day.
The book organizes habit building and system design around a four-step loop of cue, craving, response, and reward that you can manipulate to build good routines or break destructive ones.
Its central behavior-change claim is identity-based: every action you take casts a vote for the type of person you wish to become.
Designing an environment that makes desired behaviors obvious and easy is more effective than relying on temporary willpower or motivation.
