People are seeking better lives for themselves and for their families. Most want to improve their standard of living, increase their income, and put aside some money for a rainy day. Check the sales figures on the number of self-improvement books sold each year. It is an indication of people's awareness that in order to better themselves, they must continue improving their abilities. To excel in any selling situation, you must have confidence.
Confidence comes first and foremost from knowledge.
You have to understand yourself and your goals in order to develop an attitude of self-confidence. You must identify and accept your weaknesses as well as your special talents. This requires a personal honesty that not everyone is capable of exercising. In addition to knowing yourself, you must continue to learn about people. As you do to yourself, you must also do toward others.
