What is the most worst thing to do?
If you betray someone who trusts you than any one in the world - that is the worst thing you can ever do!
the worst thing to do is to be useless, unhappy, and poor. Remember: The most important thing in life is to be rich. But being happy is more important. And being useful, the most important of all. Bottom line: Being happy and useful are so important, it isnt classified in life, it's classified in living.
