So what does it mean?
- If you are good at something, keep doing it. If you're in business it is because you know how to do something. If you want to be great in business then you should focus on being able to do what you do better than anyone else.
- Don't get distracted by fads or whims. Trends come and go but your core business should be your focus.
- Make the main thing - the main thing. Remember the customer is king not the opinions of the fashionista.
