Why waste time.

I was just reading on  another post about a woman who lost her job to a layoff. She was saying that she realized after getting upset, that she was glad it happened. That she didn't really care for the people or the job.  I left a comment about the woes of my job. As I hit the publish button it dawned on me. Why am I letting my job dictate the mood of my day or stress me out. I don't know about anyone one else, but I tend to do that. We can't change it if other people are cruel and unhappy people. But we can change how we let them affect us. For example when people are rude to us. Maybe someone takes your parking spot.or cuts you off. We tend to dwell on it. Which only makes us madder. It doesn't affect them either way. But we have just ruined our day. Yes we , not them. There's so much that can go wrong in life that upsets us or worries us. Why add to  it. My daughter once asked me a question that rings so true. Are you going to remember this in 5 years. If  not. Why waste time and energy stressing about it. I need to practice that rule of thumb.
