What are the importance of salesmanship?

Good salesmanship involves honesty, concern for the customer first, a friendly personality, ambition and self-motivation as well as self-discipline. Above all, a positive, optimistic attitude will bring forth not only a lot of money but happiness and freedom only few people will ever enjoy. Never sell something you don't believe in, and always hang out with positive, successful people. Negative people are not your friends. Run from them.
