Be a gentleman.
Dress well.
Don’t overdo it.
Wear a nice timepiece.
Don’t be late.
Shake hands.
Be respectful.
Hold doors.
Tip generously.
Should be standard for every guy.
Everything that was once hard, with enough repetition, becomes boring.
And you become a master by repeating it enough times when it’s boring that you find out something new that makes it hard again.
