The first resource you should look at is your company. It is in the company’s interest to develop your productivity as fast as possible and sales training has to be a part of that. As a minimum you should expect one training course that gives you professional development once a year. A new sales professional should expect an induction and introduction to selling course. A more experienced professional should expect an advanced course (SPIN, Needs Based or Solution Selling, Major Account Development) again at least once a year.
Another easily available resource is your local bookshop or library. The topics of interest are to be found in Self Help, Motivational, and Business as well as Sales Training. I have often found that books are not good value in terms of ideas per book. This is particularly true of business books which tend to pad out a few ideas with hundred of pages of examples or stories or quotations that illustrate the idea in action. I sincerely hope you feel that this eBook is good value in terms of ideas per page!
Nowadays the best resource available to anybody is the Internet. If you enter as a Google search term any of the chapter or section titles you will get thousands of hits. One of the reasons I structured this book this way is that you can get specific help reasonably easily, but I have never seen a book that provides a framework for future research. What I hope this eBook does is give you an end to end understanding of what it takes to Develop Yourself As a Sales Professional. You can deep dive on topics as you need, or as you become interested.
