The Key

Vehicles and machines are lifeless without key.Key moves them and long distances become shorter.Key is the main key for reaching destination.
In every walk of life diligence is the key to success and happiness.A lock,however big it is, opens after all with its specific key. When key is lost the lock is useless and it is where lock master to play his role. In my view every thing in this universe has its key, we know it or not.
