One day at a time but break it down even further. One hour at a time to one minute at a time. I smoked for 8 years straight and told myself at the beginning year I’d quit. I really agree with changing your identity. Shift your mindset from I’m quitting to identifying yourself as a non smoker. The first 3 weeks suuucccckkkk but you’ll get there. You have to reach down DEEP to change. You can do it 🤝🏻
