Future son…  No need to read the entire book, here are the important ones.

Nothing is more important than family.
You can never overdress.
Don’t be afraid of pickup games.  It’s the best way to learn.
Own your own baseball mitt and golf clubs.  All other athletic equipment can be shared or borrowed.
Never leave a job without securing your next employment.
Have a signature dish, even if it’s your only one.
Be quick with a “Good morning.”
Be a regular at your local flea market.
Keep a schedule.
Wear a sports coat when traveling by plane.  It has easily accessible pockets.
Live in New York.
Start a band.
A T-shirt is neither a philosophy nor an advertisement.  Its a shirt.  Wear it plain.

And from your future Dad, the most important one…  BE YOURSELF.
