I recommend There Is A Business For You for anyone who is considering a change in their career. This is not a cookie-cutter approach. The course results are individualized based on my answers. Not only did this course help determine what type of business is most suitable, but it also required an internal examination of myself. This course is helpful to guide anyone to the right business or assist in other decisions such as opening a new location, offering a new product or service under a different brand. Even though, I have been in business for over 30 years I found this course to be invaluable as I considered expanding my business. I needed an objective appraisal of myself, and my business type and this course was it. I saw myself and my business from a perspective I had not explored previously. This course helped me answer questions that I didn’t know I needed to ask. It required me to take a hard look at my likes and dislikes about the type of work I wanted to do and how much I effort I was willing to expend on this new idea. This course helped me examine my commitment to a new endeavor, the amount of time and financial resources it would require all within the parameters of my current status. Most notably, I learned that that I did not want to invest resources in this new business. I was surprised and relieved when I received the feedback at the end of the sessions. All things considered, I’m thankful I discovered, There Is A Business For You before I invested my time, money and emotional resources in a venture that is not right for me! Barbara K.
