"Life's little instructions"

I discovered a great list, called "Life's little instructions".
A 95 year old, successful man named William Snell wrote it for a young friend on 1993, the year I was born. And I loved it!
I think old people are mighty interesting. I have a feeling that they all, even if they hide it, know how to truly live life. (Gotta go visit my grandma!) 'Cause they've lived their life, they've gone through it, they've had to weather its heavy storms, they've fallen and gotten back up again, or they may know just what not to do. I could be wrong, each person's a whole world.
But to me, when a person lives well, its a privilege to take sips of the richness of the vintage wine their life created, and see what we'd like to make of ours...I would've loved to meet this man.
Each of the next points could get me talking for hours, but I'll leave it to your imagination.

Cheers to this rich glass of wine!
