I believe that a smile is the attribute of a positive attitude, both for yourself and the perception of others.

All things being equal, people want to do business with their friends.

The best way to do business with a liar is confront them with the truth. Tell them that you do business as a partner. If your lying customer still can't see the light, tell him that you may not be the best choice for business, and that you think you have someone that can serve him better. Then, refer him to the competitor that you hate the most.

Trust is not spoken, Trust is a feeling.

Trust is not a request, Trust is earned.

What is a positive attitude? The simple definition is the way you dedicate yourself to the way you think. Interestingly, it's also the definition of a negative attitude.

I put myself in front of people who can say yes to me, and I deliver value first.
