Working out is about the numbers and continuous improvement. You just have to be better than the day before and you WILL get great results. You can't get better if you don't measure where you are so you can see the numbers improve. What does that have to do with marketing and advertising? Everything, actually... Real marketing is about the numbers and continuous improvement. You make a good ad campaign, you have the ability to measure many aspects of the campaign, you continually improve the aspects of it that are not performing as well, and then you get continual growth and improvement; It becomes an eventual big WIN. It's inevitable.
