I gotta say that there is a lot of really good advice there

but quite a bit of it makes no sense to me either

What ones don't make sense?

I'll tell you by sorting the list into groups based on my opinion...

Very good advice:
Love deeply and passionately. You might get hurt, but it's the only way to live life completely.
Never drive while holding a cup of hot coffee between your knees.
In disagreements, fight fairly. No name calling.
Never remind someone of a kindness or act of generosity you have shown him or her. Bestow a favour and forget it.
When you get really angry, stick your hands in your pockets.
Accept the fact that regardless of how many times you're right, you will sometimes be wrong.

Not so good advice:
Take along a small gift for the host or hostess when you're a dinner guest. A book is a good choice.
Don't marry a woman who picks at her food. (What is so bad about that?)
Purchase one piece of original art each year, even if it's just a small oil painting by a high school student.
Never pick up anything off the floor of a cab. (What if it is a 100 dollar bill?)

Makes no sense to me:
Accept a breath mint if someone offers you one.
Never give anybody a fondue set or anything painted avocado green.
Plant zucchini only if you have lots of friends.
Never be photographed with a cocktail glass in your hand.
Leave change where a child can find it.
When travelling the back roads, stop whenever you see a sign that reads "Honey for Sale."
When your dog dies, frame its collar and put it in a window facing west.

Unsure of authenticity of the advice:
Eat a piece of chocolate to cure bad breath from onions or garlic.

Not so good advice:
Take along a small gift for the host or hostess when you're a dinner guest. A book is a good choice.
Dinner parties are where the host cooks a really nice dinner (which you don't have to pay for) and you dress up nice and eat. Usually, most people bring a bottle of wine. So this advice is to say that you should bring something along that is different.

Don't marry a woman who picks at her food. (What is so bad about that?)
I think it means that if she does that, she is picky in life. (Very old fashioned and I don't agree with it either)

Purchase one piece of original art each year, even if it's just a small oil painting by a high school student.
Artwork is colourful and can add a nice appearance to your home. So it is saying that it is nice to add more to your home in this way. I like art, so this is something I would do.

Never pick up anything off the floor of a cab. (What if it is a 100 dollar bill?)
It's basically saying that it is a grotty place. Money is grotty as it is, so that is ok to pick up, but anything else, be weary. It will be covered in germs.

Makes no sense to me:
Accept a breath mint if someone offers you one.
A polite way of saying that you have bad breath.

Never give anybody a fondue set or anything painted avocado green.
I think because fondue sets hardly ever get used and avocado green is a horrid colour.

Plant zucchini only if you have lots of friends.
Plant a zucchini and it grows like wild. Basically, you will have too many for you to eat, so you will need to give some of it away.

Never be photographed with a cocktail glass in your hand.
I think this one is old fashioned. Makes people think you are an alcoholic.

Leave change where a child can find it.
I don't know why you would. I disagree with this one too.

When travelling the back roads, stop whenever you see a sign that reads "Honey for Sale."
Would you rather buy from a supermarket and wholesaler or would you rather buy something from a person home grown or made?

When your dog dies, frame its collar and put it in a window facing west.
No idea why it should face west, maybe it is so it faces the sunrise/sunset.

Unsure of authenticity of the advice:
Eat a piece of chocolate to cure bad breath from onions or garlic.
Would you rather your breath smell of chocolate or garlic?

Well you've given more sense to it emily, but I wonder if chocolate would really take away bad breath from onions or garlic, I would think that only a breath mint or mouthwash could do that and chocolate doesn't really smell like anything to me tbh, plus I would think that onions and garlic have a much stronger smell.

Garlic and onion breath is horrible! Chocolate does have a nice smell and it is sweet

Chocolate has never appealed much to me and I've never particularly like the smell of it, but it would still be better than onions or garlic I think.

But to tell the truth, I hate the aftertaste after eating a lot of chocolate
