Leave your Comfort Zone - Get to Know Yourself
A zen koan (short story) tells of a boy who was training under his father as a burglar:
The boy followed his father on a burglary one night and once inside the house, his father intentionally made a ruckus and fled the house. The boy darted to the nearest closet and his heart began to pound furiously as the home owners rose to see who was in their house. The boy had been given very little training, but the adrenaline of this moment was all he needed to be able to do anything he needed to do to prevent being caught. Eventually he made it out of the house undetected, and while he was not pleased with what his father had done, he had learned many lessons that night.
Often times it is important to leave your comfort zone and throw yourself into new situations where, if you think about it, you might not be entirely sure of yourself, but if you just do it you will find a way to get through it. This doesn't necessarily have to involve adrenaline - it can apply to cooking a new meal, changing careers, taking up a new sport, or virtually anything else.
Don't forget - this also offers a great way to observe yourself. Once you are thrown into a new situation, take a little time to observe your actions, your words and your feelings. You never know what you will learn about yourself.
"Observe all men; thy self most." - Benjamin Franklin
