Worry

Is there anyone out there who does not worry?  Is anyone just that confident about everything? Even if it does not turn out the way they thought it would, they still didn't worry, whatever the outcome?
For some of us it seems that worrying is a part of life, sad to say.  For me praying helps, but the doubt and worry sets right back in; and the saying goes - to worry is to doubt God.
Maybe I should stop worrying.
