From my profile ~
"People search for the meaning of life, and we are fortunate to live in an era where that question has been answered; the meaning of life is to give your own life meaning.
Nobody can do this for you, it is your duty to exhaustively seek through life to find the truth in things for yourself, and to define yourself."
Because life ends, it is therefore precious, and it is the only one that you get, and you therefore cannot allow anyone to define your life for you, or you will be living someone else's life, not your own.
