◐Partially SupportedWhen a habit is broken, resume the routine without self-judgment to prevent a single lapse from becoming a pattern.

◐Partially SupportedA committed smoker needs to attempt quitting seven times before achieving permanent cessation.

◐Partially SupportedSelf-recrimination after missing a planned behavior can create negative rewards, reinforcing avoidance.

◐Partially SupportedWillpower can be predicted by behavioral characteristics, with minimal influence from genetics.

◐Partially SupportedDeveloping an 'implementation intention' or a concrete plan for what to do when a stressful situation arises is crucial for avoiding relapse.

◐Partially SupportedAround the third or fourth attempt to quit smoking, individuals may shift from viewing lapses as moral failures to seeing them as opportunities for scientific experimentation.

◐Partially SupportedWillpower alone is often insufficient for smoking cessation, especially under stress.

◐Partially SupportedRelapse after the first cigarette often occurs due to a lack of a pre-existing plan to manage lapses.
