Remind yourself and others, it is their choice, you can choose to either let every small thing affect you in a negative way, or you can choose to let it affect you in a positive way, a mistake is not a bad thing, you learn from mistakes. You are stuck in traffic? Everything happens for a reason. You are lucky, who knows what would have happened if you would not have been stuck in traffic!? Choose to be happy, choose to be grateful, believe that there is a good reason behind everything even though, you might not understand it at that moment!
“I, not events, have the power to make me happy or unhappy today. I can choose which it shall be. Yesterday is dead; tomorrow hasn't arrived yet. I have just one day, today, and I'm going to be happy in it.” - Groucho Marx
