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.

On an afternoon several years ago, my brother-in-law opened the bottom drawer of my sister's dress and picked out a beautiful skirt."Jan bought this the first time we went to New York, at least 8 or 9 years ago.She never wore it.She was saving it for a special occasion." he said.I guess this was the occasion: it was the funeral (葬礼) of my sister, after her unexpected death.

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 hack 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.
