"Picking a Fight" is not something our parents told us was a good thing to do. Perhaps we need to rethink this advice. Retirement might be the perfect time to look around and pick a fight with some bully.
We like to trust people. That is a good thing. However, sometimes we can be taken advantage of if we are not careful. As we grow older this can become a very serious problem.
I know some people who say they don’t know what they would do if they were retired. My experience tells me that you will, or can be, very busy. Busy, but busy doing exactly what you want to.
