Live for Today

When my mother died back in 2010, one of the things she kept on saying is that "it's not fair. I worked my whole life and had all these plans."
She did that. And then 4 months after she retired at age 65, after having worked most of her life to save up for her retirement, she got very sick. It turned out to be brain cancer and she died in a hospital about a year later. Except for a few months when she got better, she never got to enjoy one minute of her retirement.
When I was young, about 19, my friend Vern's mother died in her sleep. A very young woman in her early 40s, she showed no signs of any trouble. Then one night, Vern's father came home and found her dead in the bed.
Today, came the sad news that Jim Flaherty, the long time finance minister for the federal government had died suddenly, only one month after resigning from that post. He had plans to join the private sector, but I'm sure after a long lifetime of working to make his way, he was looking to enjoy a long and happy retirement. He was 64.
My mother was 65. Vern's mom was about 45. My friend George died at 18 in a car accident. Just like that. 
You never know when your time is up.
The best you can do is live for today, and don't worry about tomorrow, as they say in the song above. That doesn't mean you don't prepare for a long retirement. You do. But, you never know when your time will be up.
When you get older, as you get older, you learn that life is not infinite. You will only be on this earth for a relatively short time. Make the most of that time, knowing all along that in most cases, you don't know how long that time will be. Live for today. And tomorrow. But mostly, today.
