The Silver Lining
Most people would agree that a heart attack is a terrible thing. And it certainly is, as it might kill you and if it doesn't it will change your life significantly. But in Lerher's case in his book A Bus of My Own, some of the changes were for the better.
The first thing he did when he woke up was to make lists and organize his life, which certainly is a good thing. Anyone can benefit from a little more organization and coherence. He decided that he needed to pursue his ambition of writing fiction more avidly, and he also resolved to be more serious about his collection of bus memorabilia.
Another change that might be seen as not very enjoyable, but certainly beneficial, is the change in his diet. His former diet consisted solely of comfort foods and fast food, which was probably a proponent in his heart attack in the first place. He had to change his diet to far more healthy foods, which he did not enjoy eating quite so much but it probably improved his overall health in the long run.
Before his heart attack, he was a heavy smoker. In fact he described it as being an important aspect of his life, and after his heart attack he never smoked again. Luckily this was not a reluctant change; it simply never crossed his mind once during or after his recovery and what was once a main ritual in his daily life just faded away. This was clearly a good thing.
A heart attack is a very bad thing, and changes are not always good, but these three things certainly changed Lerher's life for the better.
