"Don't count the days, make the days count." ~ Muhammad Ali
It can be dangerous to start counting down your days, because you want to make each one count. But many times there will be an event coming up that makes you start counting down how many days until it arrives. But each day between now and then is important, and you don't want to breeze over any part of your life just to get to the next, seemingly better part. Putting the most of yourself into each day will make it so you never have any regrets about how you spent your time here, and you'll know that you really did make it count each day.
