We never know what gonna happen 1 sec from now. If it happens what you've known, that doesn't mean that you know the future.
Today is very important and NOW is more important for today. If you are in love with someone tell it today. You have the best smile when you smile from your heart; smile today. They are desperately in need of help, show your kindness today. I always remember treating myself with nice chocolate drink, I would suggest go for one today. You bought a lovely dress the other day but haven't got the chance to put on; wear today and be at your best. Start today and be yourself today.
