Recently Warren Buffett was named the richest person in the world with a total worth of $62 billion.

If you were Warren Buffett, would you retire once and for all? He's pretty old and it seems to me it might be worth relaxing for the rest of your life once you hit the title of "Richest person in the world".

Instead he is still plugging away. In fact his yearly salary is only $100,000 not including capital gains from positive investing.
