True, this is what most people don't get, they would feel they are being persistent, they have not given up but in reality they are just doing the same thing over and over again, there would be no change and all your efforts would be to waste.Yes in starting and running a business persistence is is key,but if you are doing the same thing over a long period of time and there is no difference in results then there is need for a change in strategy and evaluation of the methods that have been adopted.
