BE a communicator. Great communication is the key to success in many areas of life. In business, proper communication dispels fear and promotes confidence. Communicating ideas with staff and coworkers on how they can be successful, along with notifying customers of deals or services they may benefit from, are great ways to be a positive and effective communicator. Effective communication also helps promote business through word of mouth.
I hope you can make some of these "BE attitudes" your own. Happy selling and sincere regards.
