Everybody has had at least one experience from which he knows the meaning of life. This time, which took place several years ago, but seems as if it just happened.

He took the shirt and put it on bed, with the other clothes we were taking to the funeral. Then he closed the drawer and turned to me, “Don’t ever save anything for a special occasion. Every day you’re alive is a special occasion.”

I’m thinking about his words, and they’ve changed the way I live my life. I’m spending more time with my family and friends and less time in committee meetings. Whenever possible, life should be a kind of experience to enjoy, not to suffer. “Someday”and “one of these days”are losing their importance on my vocabulary. If it’s worth seeing or hearing or doing, I want to see and hear and do it now.

Ever since that day, I have been trying very hard not to put off, hold back or save anything that would add laughter and color to our lives. Every morning when I open my eyes, I tell myself that every day, every minute, every breath, truly is a gift. So cherish every day and find the true meaning of your life.
