Some say that life is a rollercoaster. I say, "life is a highway!"
Some say that today is the first day of the rest of your life. I say, "but today is almost over!"
Some say that life is pain. I say, "cheer up!"
Some say that life is like a box of chocolates. I say, "yum!"
Some say that life is unpredictable. I say, "life is great!"
Some say that life begins at conception. I say, "life must have started in the simplest possible way, as a cycle, a natural chemical reaction that repeated itself, spinning off byproducts, some of which stayed around to maintain and develop the cycle and that at some stage, the little cycle acquired a cover of protective chemicals, to separate its own reactions from the general milieu. I also say that when the cover eventually enveloped the cycle and broke free of the mineral surface, the first cell was born!"
These are few circumstances where I see things differently than other people. Your mileage may vary.
Some say life is an adventure. I say, "life is THE adventure!"
