When I was younger I was afraid to dive head first into a swimming pool.
Then one day I saw a little kid doing flips off the diving board into pool."If that kid can do it I know I can," I said to myself. So I started doing flips off the diving board.No problem!I soon realized a dive is half of a flip.So I gave it a try and it worked.After a little practice I became a really good diver.Do the thing you are afraid to do and do it again and again.You will eventually replace fear with courage.
