I have learned that no one is always right. No one knows it all. Systems keep changing, we keep changing. Keeping an open mind, looking at others points of view is a good thing. It doesnt mean one person is right and the other wrong.
Loosing, or being a loser. Everyone has experience it at some time. When I use to play sports you have a winner and a looser. I had no problem loosing, being a looser if I did my best and we lost. It was a good competition and someone else won, I could feel good about being a looser. Or now I play a game with someone and you have a winner or a looser. If you do something and enjoy it, have fun doing it, you can be a looser and its not a bad thing.
