The secret to quitting, I decided, was never to smoke again. Ever. Close the door on it totally and forever. Not just "I hope", but not to open that door ever again. So all I had to do was not to smoke.
And I decided I could do that. I didn't try to figure out the rest of my life, I didn't cement my plan into stone, I didn't even announce to anyone I was quitting. I quietly shut the door and refused to open it ever again.
The Most Effective Way to Quit
Close the door to smoking, do not hold on to it as an option. Be willing to close the door and never open it again. NOPE.
