Golf is a spiritual game. It's like Zen. You have to let your mind take over.
Don't give advice unless you're asked.
My parents didn't play golf.
What makes a great golf course is continuity and variety: right-to-left holes, left-to-right holes.
You could argue that if the average golfer plays a golf course with 430-yard par 4s and they always miss the green, that's good practice. It's definitely great practice to play a course that's too long for you.
Keep your sense of humor. There's enough stress in the rest of your life not to let bad shots ruin a game you're supposed to enjoy.
