Leader

I must say, I'm highly anticipating the reasons behind some of the words posted. My first thought, also happened to be "happiness," but here's why I opted for "leader":

My idea of a personal mental nirvana doesn't exist in the English language (nor any others that I know of). Happiness/joy/glee/gaiety has become so arbitrary (along with love) that it has come to be the definition of much lower descriptions that cannot live up to the meaning that needs to be expressed. Happiness is nearly synonymous with contentment or more scarily, even apathy. A more desirable feeling would be ecstasy (intense joy or delight; rapture according to my dictionary), but this still doesn't capture what people really yearn for. As I am not trying to have a semantic argument based on this point, for clarity purposes I'll use "777" below to describe this non-word.

In my opinion, 777 cannot be just achieved whenever. [Yes, I know this is about to start an argument.] 777 needs to be earned. By this, I mean a person needs values and a philosophy on life in which to measure herself against. Without a solid system or understanding of one's own beliefs, desires, and passions - true 777 will never be achieved. "Happiness" can be achieved by hanging out on a beach all day or enjoying a nice glass of wine. While these things are wonderful and possibly deserve a close 2nd place, it isn't what we all live for. If it was, none of us would have gone to college or participate in careers.

Instead, it takes a "leader" to lead herself to follow her dreams, focus on the important things in her life, and succeed at those things; 777 is the feeling/thought achieved. Leaders can enjoy happiness that other forces or people have created (such as wine, beaches, nature, books), but will understand that the most important task is to create: create goals; create measurements; create solutions; create a life. Creation may mean creating happiness for others, wealth for oneself, literally creating a life for someone, or creating a solutions to bad beer or global warming. With any of these, the satisfaction attained could never be explained by, nor caused by "happiness" as we know it. It takes a leader to lead one's own philosophy and dreams, lead others to assist, and lead oneself to one's own personal 777.
