I totaly agree wid you on this is the only way to push you up from the fear

Example -

We always have a fear from failing in exam ?

what we do for it
push ourself harder to get skilled on that subject or topic which indirectly overcome our failure for exam

moral of the story if you are having fear , you do something at least something to get rid off ( in this case at least you push yourself to get passing marks right )

these small steps of life makes us more strong

once fear is gone - after that it wont be a fear anymore
