He had many great sayings that were not only humorous, but revealed a deep understanding of life. The most memorable were:
Stupid is supposed to hurt.
Without an education you are not much more than obsolete farm equipment.
Work smart because you will never work harder than a mule, or cheaper.
The first 20 years of your life are where you are supposed to fill your head with the things you will spend the rest of your life selling. Pay attention and make sure you have plenty of inventory.
If you don't want people talking about it, don't do it.
Beware of people telling you what you want to hear. When someone has his tongue in your ear you need to know where both of his hands are.
Just because no one ever finds out about it doesn't mean it isn't a sin.
I think I would have loved to spend some time with your Grandfather. ;) Thanks for sharing some his sayings. There was a great amount of common sense then. Something that is SORELY missing today.
