The most valuable thing

Three friends were sitting drinking coffee together talking about many different things some important and other not very important. One thing they discussed was “What is the most valuable thing in the world?” After some discussions, two of the friends noticed that the other friend was not saying any thing. One asked him “What do you think is the most valuable thing in the world?” without hesitation, he replied, “I consider advice is the most valuable thing in the world”. His friends thought about this for a moment and then one of them asked him “What do you think the most worthless thing in the world? ” without hesitation, he replied, “I consider advice is the most worthless thing in the world”. How can it be both valuable and worthless? “Well” he answered, “it is easy. When you give somebody good advice and he takes it. Advice is the most valuable thing in the world. But when you give a person advice and he doesn’t take it, it is the most worthless thing in the world.”
