You take it personally when something doesn't go your way now. It may feel as if someone is purposefully trying to rattle your cage to test your reactions. Regardless of anyone else's actions, the real lesson here is about your behavior and not theirs. Forget about trying to analyze why other people do what they do; concentrate on the path ahead of you. After you acknowledge a recent mistake, let it go. Author Maria Robinson wrote, "Nobody can go back and start a new beginning, but anyone can start today and make a new ending."
