With the investment we make in our business time wise, it is also critical to invest in the improvement of our skills. Depending on the company, they may or may not provide you with sales seminars and info to help you develop and grow professionally. It is up to you to do it on your own regardless of the assistance your company provides if you want to grow your business.
Picking up a good sales book a week is a great way to start. Also look into seminars and blogs. There is a lot of great resources out there that are not expensive or in many instances, no charge.
Make a committment to hone your craft and treat yourself to a good business book or blog, like this one LOL or better yet, both.
