These are parts of Anna Quindlen's commencement address to Villanova students in June of 2000. It's advice I try to live by and intend to instill in my son.

1) No man ever said on his deathbed I wish I had spent more time in the office.
2) You will be the only person alive who has sole custody of your life. Your particular life. Your entire life. Not just your life at a desk, or your life on a bus, or in a car, or at the computer. Not just the life of your minds, but the life of your heart. Not just your bank account, but your soul...
My favorite part (condensed)
Get a Life. A real life, not a manic pursuit of the next promotion, the bigger paycheck, the larger house...Get a life in which you notice the smell of salt water pushing itself on a breeze over Seaside Heights, a life in which you stop and watch how a red-tailed hawk circles over the water gap or the way a baby scowls with concentration when she tries to pick up a cheerio with her thumb and first finger. Get a life in which you are not alone. Find people you love, and who love you. Pick up the phone. Send an e-mail. Write a letter. Kiss your Mom. Hug your Dad...And realize that life is the best thing ever, and that you have no business taking it for granted.
