Shakespeare said "There is nothing good or bad, but thinking makes it so". How true isn't it? The most hated enemy of one is the most loving person to another. The perception power of mind is such that it is how we channel our thoughts in an optimistic or pessimistic track. 1.4kg weighing human brain which is the thought center holds the key to success or failure. It is how we react to situations and people that determines end result.
A famous saying goes "Minds are like parachute, they function only when open". When we perceive we get help from stereo typing that has been generated in our mind by our experiences. A chain reaction of stereo typing, called ceiling effects are created within our mind that does not allow it to open beyond the boundary formed by stereo typing.
Winston Churchill said "The price of greatness is responsibility over each of your thoughts". Let our perceptions guide us but not rule us when we face situations and people.
