Life is a grindstone. Whether it grinds you down or polishes you up, depends upon what you're made of. Life is an echo. What you send out - you get back. What you give - you get.
Life is a roller coaster.
You can either scream every time you hit a bump or you can throw your hands up in the air and enjoy it. Life is a waste of time, time is a waste of life, so get wasted all the time and have the time of your life. Life is full of surprises. Life is hard, no one makes it out alive. Life is like a game of cards.
