In every man there is something from the person, but not every man is a person. Personality is not the one who wants to be a person. Personality is the one who feels the need to be yourself. Who is strained in the name of the target, he can become an influential person - the person in form but not in substance. He can call himself a personality, and his fans can call it personality. Truth is found later. Only when a person begins to learn their delusion is cleansed of its essence. It starts improving personality - development.
And then one understands. Life constantly presents his spiritual, mental and physical lessons for self-discovery.
From all this: 9/10 need to feel and understand, and 1/10 is necessary to survive. From this 1/10: 9/10 be learned through experience, and only 1/10 - through suffering. This is only a small fraction of the whole number. Experience shows that the share of suffering is increasing, because people do not know how to think with love.
