My philosophical core (warning, I tend to get rhetorical when given the chance):
I have come to the working conclusion that the most important thing I have to do in this life is love. People, my relationships with them, and happiness are paramount in my life. We are all in this thing together, it only makes sense to care.
Furthermore, an absolute and boundless curiosity of this world fuels my motivation. The idea of mastering the arduously accumulated insight of my predecessors so I might stand on the brink of understanding, seeking to push its very limits through my own will, ingenuity, and experience, defines my ultimate purpose. I very much identify with Carl Sagan when he said “we are a way for the cosmos to know itself,” and, also like him, I have always found the challenges space exploration present to be the most fascinating. I seek to extend man's presence in the universe.
I believe in the power of the human spirit to overcome. A person's will is one of the strongest forces in existence and I have ultimate confidence in the potential of mankind.
So there's that. And while I am a thoughtful person, I am rarely serious. I like to do hoodrat stuff with my friends.
I take risks and never miss a moment to laugh, to love... to live.
Hakuna Matata, It means no worries.
Oh, and I am a ENFP personality type (the champion). :D
