answer:I think it is as simple as almost everything is temporary. If you live you move on to a new day and new things. We do learn from experience, and learning means we can make better decisions in the future. Adversity forces us into change, and change can be good. We all know people where it hasn’t happened. Where their life took an awful turn and the results were devastating. About the gas. In America cars are made to not be accurate for the final amount of miles left. I saw a show about it 10 years ago, maybe things have change. The cars in German were accurate by contrast. Things mostly work out for me, but I have some health issues that I would have been much much better off without. Some things about my health problems have helped me with other subsequent problems, and I also appreciate smaller joys in life because of my health struggles I think, but never having had them would have been better.
