I suppose this is a cliche, but as I look back on my life (I'm approaching 63), it's not the things I did that I regret - it's the things I didn't do.
That one statement pretty much sums up my philosophy on life. I regret never asking the girI in my high school English class on a date. I regret not spending more time with my kids when they were younger. I regret the extra days and hours I chose to put in at work rather than with my family. I regret the vacations we didn't take because we thought we couldn't afford them, or I thought I shouldn't take the time off from work.
There is nothing more important than family and good friends. Riches and possessions can't begin to substitute. Anyone who says differently is lying to you and to themselves. Sure, wealth may give you more choices, but you can't buy a child's laugh, or a loved one's caress.
I wouldn't presume to advise anyone to do anything, but I WOULD advise everyone to do those things that you've always wanted to do, but for which there was never 'time'. You don't get another chance (as far as we know, anyway), so this is it. So, tell someone you love, how important he/she is to you. If you have a dog - take him for an extra walk around the block, and give him a treat when you get home.
