Fear is a natural, involuntary response to a perceived threat.
Fear exists to help you survive in an often harsh and dangerous world.
Worry is something altogether different, however.
Worry is a story you tell yourself about fear.
Fear is immediate and about the present moment.
Worry, on the other hand, takes you out of this moment.
Worry is the projection of fear into the future; it is the fear of things to come.
But the future is not inevitable and to worry about it does nothing to improve it.
Worry prevents you from taking the necessary actions in this moment to improve your future, the very future you are worried about not being able to improve.
And while you cannot simply decide to never experience fear, you can decide to not add to fear with worry.
