My "Father" who I frequently refer to as (sperm donor) taught me that cheating on your wife will end in divorce, and that you will become that far off relative that nobody ever sees. (Thankfully)
My DAD taught me:
-If it's got tires or ****, it'll cause you problems! (Still married to Mom after 25+ years)
-How to fish
-How to hunt, and take care of the land.
-Many times silence is the loudest thing you can say.
-Don't be in a hurry, wherever it is you're headed, it'll still be there when you arrive. 2.5 Million miles in a UPS truck without a scratch taught him that.
-Don't worry about things you can't control, things have a way of working out.
-You can love you wife, and not have to be with her every second of every day.
-Learning never stops, no matter your age and experience.
-When things are at their worst, keep a level head and work it through. This has been especially valuable as a Paramedic, sometimes you have to have ice water in your veins.
Even my Father-in-Law has taught me a few things:
-My favorite: cut to size, kick to fit.
-The Andy Griffith Show, has many of the answers to life's questions.
