I work through it until I get it right. I get the process started, and my taxes done. Similarly, to quit smoking, just get started. Don't worry if you don't have all the information or if the time isn't perfect or if you don't think you can quit. There never will be the perfect conditions for you to quit.
Time waits for no one, as they say, so quit today or face the consequences tomorrow.
Not tomorrow or sometime soon. Seize the moment and make it happen now. Now is the only time anyone has. If someone told you to smoke 7,300 cigarettes today, you'd call them crazy. Likewise, if you worry about not being able to smoke tomorrow because you quit today, you may find yourself panicked and unable to quit.
