Worry doesn't get you anywhere but it does make you think

The phrase "don't worry" isn't always the best advice usless it's followed by "make a plan."  Worry is like fear in that it can protect us.  When we are fearful we put up our guard to protect ourselves.  Worry can help us as long as we use it wisely.  Use it to have back up plans.  If you make no use of worry, it is a waste of brain power!
