This is a short list of things I have learned over the years.
Kid’s, life is hard, get over it.
Good judgment comes from experience.
Experience comes from bad judgment.
Authority can be delegated.
Responsibility cannot be delegated.
You can’t demand respect.
Respect must be earned.
Don’t pick a fight with an old man.
If he can’t beat you, he’ll probably just kill you.
And lastly, beware of an old man in a profession where men die young.
I hope you will find something in this that will be helpful.
Just remember; life is good, whether you like it or not.
