"In three words I can sum up everything I've learned about life: It goes on!" (Robert Frost)
Yes, it does... life continues whether you decide to make the most of it or not. So give this some thought: You can dwell on the past or you can take delight in the future. You can march forward with confidence or you can stand still. You can accomplish great things or you can think small thoughts. You can make the world a better place or you can make the world a bitter place.
Realize your potential, fulfill your dreams, and the focus will move away from yourself and onto others. Indeed, life goes on - so get out there and make every moment you have count!
