I was giving a shiur about how a yid has to be in control of himself 24 hours a day, I was challeged – I was a heavy smoker 20 hour a day, six days a week, for 30 years. I was actually smoking at that moment.
I put it out and never lite up again, that was three years ago.
Yes, I still miss smoking but – every yid must be in control of himself!
