I disagree with the sentiment, but I love the analogy of horseradish. This made me want a sandwich.Advice is like horseradish. When it is appropriate, it can be the perfect enhancer. However, it's usefulness is limited, and you never give horseradish to someone who just wants mayonnaise or ketchup. Even when you do offer it, sometimes less is better.
When people really want advice, they'll ask for it. When they want empathy, giving advice is meeting your ego, not their needs.
