Years ago, I had some friends who were smoking one or two cigarettes daily. I had warned them almost every day at that time.
I said to one of them:
"Now the smoking is under your control. But later it will be the cigarette who controls you".
But he ignored and replied.
"I can stop the smoking whenever I wish to do so. Because now I puff only one or two each time after the lunch and supper."
Now after 15 years I met him once again and found that his lips don't have any free time as they are clamping a cigarette in between the two one after another continuously!
Smile only the solution sometimes.
