I recently posted about "Strengths vs. Weakness" and implied that the best among us, promote their strengths and don't spend much time on trying to change their weaknesses. I also recommended that you look at a book called StrengthsFinders 2.0 which is the basis for this philosophy. A philosophy that is explained and promoted by no less than the Gallup Management organization who have been polling and interpreting people for over 100 years. They have a very powerful program for helping businesses understand themselves and their employees.
Yesterday, they released a new blog that speaks to exactly the issue of Strength building and how management can promote, understand and encourage this road to success for their own companies and the people they employ.
I strongly recommend that you take a few moments to read it here. This will be excellent information for sales people and sales managers alike.
