Introverts vs Exroverts; the golden ratio

Being an introvert is way too easy. You must have to stay alone, not bother about others and the most important of it all, have a circle of friends where the radius tends to zero. I was impressed with the phrase by Mark Twain which goes "It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt" and I was a blind follower of this. I thought that sometimes, (or rather may a times) people felt that you are genius when you kept your mouth shut and kept a large distance from the others. It was good to notice that introverts are praised for their work but are really victims of poor social bonding.
On the other hand I wondered if extroverts (people who are social) won people's hearts. But this notion too was not true. Its really a question of how extrovert or how introvert you are. Actually I noticed that people who turned into extroverts after being a introvert found that the world that introverts have are much better. You need not really bother about others and feel hurt if someone even makes a joke about you (as though someone would!!). I believe that an equal mix is necessary but am not sure if the introvert character or the extrovert character would win eventually!! Its also important to understand that a person who wishes to be an extrovert should not make or take statements personally. At times I start think philosophically, wondering if this world would be filled with people who only enjoy the company of one another but later on found that there would be no fun then if everyone was happy. It has to be balanced in nature. Physics states that the energy that the system contains has to be a constant at all times!!!
The golden ratio would be a 40% extrovert and a 60% introvert. That way you neither compromise on your self esteem nor do you compromise on your social circles!!
