Being humble and polite is often mistaken for being "weak".
Not many people (respect) weakness. P.T. Barnum once said, "There's a sucker born every minute". It's important to be seen as strong, decisive, as well as tactful to earn the respect of others. It's up to each and everyone of us to look out for ourselves. Trust like respect is to be earned overtime. Don't just give it away. That's a conman's dream!
