worry or know how not to

The future  looks uncertain,scary,hidden.we wouldn't be human if we didn't worry about things at times. We worry about our health,our parents/kids/friends,our relationships,our work and our spending... We worry that we're getting older,fatter,poorer,more tired,less attractive,less fit,less mentally alert,less everything really. We worry about things that matter and things that don't. Sometimes we worry about not worrying.
Look, sometimes it might be ok to "worry" so long there is something REALLY to worry about. What Jesus warned against is being overwhelmed with your worries which is anxiety. This is a total waste of time and energy for it is bereft of the ability to alleviate your worries,it is like chasing the wind.
