How is it that if you have a set of data, x1,y1....xn,yn with a known linear relationship between x & y (y = mx + c), and the best straight line fit MUST go through xbar,ybar (xbar average of all x values, ybar is average of all y values).
You are stuck in something called a market myopia, which is the failure of a business to realize it's scope. So what u have to do in order to expand is to think of other things related to eye lash extentions, possibly nails? or hair what ever you are interested in. Because no matter how many people want there eye lashes longer you will get FAR more customers with an expansion of products, become a "beauty" company not just "eye lash extension" company.
