I believe that life is a journey and not a destination. Take chances and be spontaneous no matter what you believe will happen in the after life.
Be curious.
Test the limits of the universe, and don't worry about finances as those things have a way of working themselves out.
You shouldn't underestimate the power of laughter and friendship. They're your safety net, your security blanket, and you should treat them well.
And even though I think I write crappy fanfictions, I do take pride in knowing that no one before in the history of the world has put those words in that order. They are entirely mine.
