Of all the sad words by mouth or by pen, the saddest are these: what could have been.

Every second, every breath, every moment is a gift.  Make the most of every situation you encounter, be as happy as you possibly can be; for happiness is merely an attitude.  Good and bad enters any life throughout it's course, how we handle the trials, and recover from the setbacks is the true test.   
Make every day special, every day memorable. Each day is a new day, leave your mark upon this good earth.  Life is a fascinating adventure, make the most of it.
