The wonderful thing about age is that your knees don't work as well, you can't run down steps quite as easily and obviously you can't lift heavy weights. But your mind doesn't feel any different.
When I started 70 odd years ago I was told that to be a success you've got to have talent, personality and luck. I've had 99.9 percent luck and the other miniscule percentage would be having had the luck to have a little bit of talent, being able to stand upright and that's it. It's all luck.
I do not have time to sit down and regret anything although sometimes I wish I had been able to see more of my parents while they were alive and have done more for them.
