I would like to get the member's views on this quote from EntrepreneursNewsletter:
When somebody challenges you, fight back. Be brutal, be tough.
- Donald Trump -

I personally think that this is the worst business advice I have ever seen published. Business is about networking and building relationships. A soft word can sometimes have more effect than being rude and brutal. As far as I know, nobody likes Donald Trump, because of his brutal attitude. He is only tolerated by those who can gain from the relationship.

My advice: Do not be arrogant and rude to people when on your way up, you usually meet the same people on your way down...
