The most powerful thing you can do to assure success in any endeavor is to focus. I am talking about complete and absolute concentration on your goal. You must know your market intimately. People spend too much time looking for opportunity around the corner and down the street that they miss the goldmine right in thier own back yard. I know because I fell victim to this myself. Somthing happens when you begin to achieve success. You start to feel invincable and it becomes difficult to see clearly. Thats why profesional athletes always train with the basics and fundamentals it helps them to keep their focus. Keep it simple and keep your focus at all times and you will succeed.
