Food for thought
One day Bill Gates went to a restaurant. He thoroughly enjoyed his meal. When it was time to pay for it, he left a $10 dollar tip for the waiter.
The waiter, confused, asked "you're one of the richest men in the world and you only leave me a $10 tip. Your son came in last week and he left me $100"
Without thinking Bill replied "he's the son of one of the richest men in the world, i'm the son of a woodcutter"
