This also applies to quitting smoking.
You make small changes.
Those changes are reminders.
Those reminders change your future.
They lift you out out the repetition rut.
They show you change.
They prove possibilities.
The nicotine keeps you coming back.
Without that reward, quitting smoking is just unlearning the repetition of the ritual to get to that reward.
Time Is The Healer
The more life experiences as a non smoker, the greater the distance grows between you and smoking.
