Worrying is a total waste of time. It doesn’t change anything. All it does is steal your joy and keeps you very busy doing nothing.
Why worry about something you cannot control? Is it hard sometimes to NOT worry? Of course it is! All I can say is whatever it is that is on your mind, think about if you can control it or not. If you come to the realization that you cannot change what might happen, then you have to let it play out. Do not let worrying steal your happiness. If the results turn out negative then it was meant to be. Stop worrying and think positive! Period.
