I tend to worry frequently about a lot of things. Being 57 years old I really ought to know better; worrying doesn’t help ! Also, my experience so far has been that whatever happens is not nearly so catastrophic as I imagined it would be….
My favorite thing to worry about is money; I never have enough ! I think that particular anxiety is endemic amongst modern Americans but is generally unfounded….
dennis' notes.... 
‘So do not worry about tomorrow, for tomorrow will bring worries of its own. Today’s trouble is enough for today. Jesus (Matt 6)
You need only worry about money when you have not got it, and then its too late to worry.
So you are right..do not worry..it’s a waste of time
