My ethos is to check and recheck, similar to what your grandfather did; it makes for less errors and improves the chance of success. Your grandfather was a smart man and he set a good example.
If people prepared themselves a little better in all aspects of life they would find a better life, but we live in a society where nnear enough is good enough (generally), and that makes for a lot of mediocrity.
Agree, it creates an "instinct" that shows with contemplative experience.
I am happy to have a grandfather like him.
Checks and re-checks really run in an orderly manner in his life.
I'm sure you are better than my grandfather because we live in an age that is supported by advanced technology.
If people live with these good habits, of course, there will not be many obstacles in leadership.
I'm not better than your grandfather, I'm just different. He sounds like a really cool dude.
