Know your numbers. One of the many reasons that I quit had to do with percentages. The odds. I needed dental work and was told that the odds of failure in smokers was 30%. A tooth implant. Costly. The consequences of my decisions were real. Another marble in the don't smoke scale. Two of our contributors here have mentioned the word percentage and I have found that concept to be useful. Quitting is measurable. What percentage of our after tax income did we spend on tobacco. Healthier is hard to measure because I do not know what would have happened and smoking is not the only factor. But my guess is that it is at least thirty percent better. Now if I could just get that number on my investments.
