Ask yourself, because this is your story, nobody else can answer for you.
Just like some advertisement for healthy lifestyle company, the slim club. They have two pictures, one before, and one after. What and who are the contributors to the success story, and how did you do it?
Success has different levels and measurements in different people, some measurement of success is related to goals achieved, and the goals may vary from person to person, and company to company.
For example: If you set your target to sell $10,000 a month, that is your measurable goal, so you make plans to achieve this target.
