Bob Burg talks about the following three principles in his booklet titled "The Success Formula":

1.  Seek Out and Find the Information – Follow “The System”

This is really all about finding someone who has the success that you want, accepting their guidance and following their system.  Make sure the system is producing results today.

2.  Apply the Information Immediately – Knowledge Without Action Is the Same As No knowledge At All

Take action now.  One trait that I found universal to six and seven figure income earners is a sense of urgency in doing the things that move a business forward.  Have 20 calls to make?  Make them now.

3.  Be Persistent – Outlast the “Nos”

Knowledge and Persistence have way more to do with success than talent.
