I once reviewed a company’s sales team.  The team was easily divided into two groups.  One was very successful.  One was not.  After speaking with the two groups, it was easy to see what differentiated the teams.  

One team’s general philosophy was, “I made ten calls today.  I didn’t make any sales.  I’ll call ten more tomorrow.”  The other team’s general philosophy was, “I made ten calls today.  I didn’t make any sales.  I’ll call ten more now.”  Can you guess which group was more successful?

Yes.  Luck does play a part in success but you can’t control luck.  You can control the amount of effort you put into a task and the quality of that effort.  The better prepared you are, the less necessary luck is to your success.

This is true in sales and it is true in every aspect of your success.
