The book has two concepts discussed- 1) 21 COMMON MISTAKES - it is known that Selling skills are the most important personal and business skill. In other words, selling skills is the most crucial life skill. As human beings, we are social animals and our natural instinct is to live in groups. It is this innate nature and tendencies which have helped the human race to thrive and totally dominate the planet earth. When there is human interaction then the skill and ability to influence, persuade, convince win over ability which is nothing but Selling Skills which are of paramount importance. 2) MASTERY -we human beings have infinite potential and have the capacity to achieve anything that one desires. What stops the human being from touching mastery, greatness is their own self -created barriers in the form of harboring and nurturing limiting beliefs acquired through conscious and unconscious conditioning. As they say, every master was once a disaster or just average and ordinary. It is one’s own resolve to commit oneself to excellence fueled by a deep intensity of purpose which sets one towards the journey of mastery. It is absolutely ok for us to be ordinary from the worldly perception in the journey to become extra-ordinary. The journey involves stretching oneself to go beyond one’s limits and confines of the comfort zone into a creative zone.
