Trust is a function of both character and competence. Of course you can't trust someone who lacks integrity, but if someone is honest but they can't perform, you're not going to trust them either. You won't trust them to get the job done.
Stephen CoveyBefore a performance, a sales presentation, a difficult confrontation, or the daily challenge of meeting a goal, see it clearly, vividly, relentlessly, over and over again. Create an internal "comfort zone". Then, when you get into the situation, it isn't foreign. It doesn't scare you.
Stephen CoveyThere are principles that govern human effectiveness - natural laws in the human dimension that are just as real, just as unchanging and unarguably there as laws such as gravity are in the physical dimension.
