Why did I decide to stop smoking?

The first step in stopping to smoke is why and there are a lot of reasons; health, money...
For me it was the thought of becoming a father, my wife´s pregnant and in about 8 weeks we will have a daughter. So I decided that I want to be a good father who does not smell like an ash-tray and wants to be in good health for future leisure activities.My wife doesn´t smoke and complained a lot in the past about my bad breath etc. but I never had the feeling to stop when someone put me under pressure, the result was that I smoked more.
