    You are about to hear a strange but true story. Legend has it that, Harry Houdini, the master magician, once claimed that he could break out of any jail cell in the world. All he had to do was walk into that jail cell with his street clothes on. 'I will be out of there in one hour. No problem!' He said. A very old jail down South heard about Houdini's claims and they accepted the challenge. On the day of the event, many people gathered outside. Very confidently, Houdini walked into the jail and into the cell and they shut the metal door behind him.

The first thing Houdini did was to take off his coat. Then, very strangely, he took off his belt. Secretly hidden in Houdini's belt, was a ten-inch piece of steel; very tough and very flexible and Houdini started working.

In about 30 minutes, that confident expression Houdini had when he walked in disappeared. In one hour, he was bathed in sweat. And at the end of two hours, Houdini in defeat, collapsed against the door, which then opened. It opened because you see, that door had never been locked. But that's not entirely true is it? That door was locked. It was firmly and thoroughly locked in Houdini's mind, which meant it was locked as if the best locksmith in the world had put his lock on it.

The mind is powerful. How many doors in your life do you think are locked but aren't? how many times have you been stuck in the mental prison of over thinking something that really had a simple solution. There is an ancient African proverb that says when there is no enemy within, the enemy outside can do us no harm.

Your mind is the most powerful force you will ever face. It will tell you lies. It will tell you can't do that. You're not meant for that. You're not good enough for that. You can't go on anymore. You don't have the energy. You must thank it for its opinion and carry on. Because as Houdini showed us the only locked doors that exist are in your own mind. The doors in reality are open and all you have to do is walk through.
