What's your motivation of quitting smoking?

Smoking is undoubtedly harmful to health but quitting it is really a tough challenge. Then what motives you most in deciding to quit smoking? I have a lot to say about my quitting story. I watched my Grandma go from a healthy and energetic woman to total skeleton and then dead in very short time during my high school years, it was horrifying-yet i still got addicted to smoke. But i really never wanted my children to see me that way and so i turned to vaping from smoking cigarettes. I am sincerely thankful that i still get to enjoy my hobby in a format which will clearly reduce the risk of smoking-related diseases happening. At the beginning i tried Eleaf iStick on official authorized website to pair with Aspire Nautilus Tank, really super marvelous vaping experience i will never forget!  So fortunate i finally quitted smoking and hope more smokers will succeed kicking nicotine addiction by electronic cigarette!
