As we grow up, we learn that even the one person that wasn't supposed to ever let you down... probably will. You will have your heart broken but you'll break hearts too, so remember how it felt. You'll fight with your best friend. You'll blame a new love for things an old one did. You'll cry because time is passing too fast and you'll lose someone you love. Life comes with no guarantees, no time outs, no second chances. So live life to the fullest, tell someone what they mean to you, speak out, dance in the rain, hold someone's hand, comfort a friend, fall asleep watching the sun come up, stay up late, and smile until your face hurts. Don't be afraid to take chances. Take too many pictures and love like you have never been hurt...because every second you spend upset is a moment you'll never get back.
I like geography best because mountains & rivers know the secret: Pay no attention to boundaries.
