That is an emerging trend in personal development. Forget your weaknesses and focus on your strengths. Collaborate with others to cover for your weaknesses.Wayne Bennett, one of the all time great rugby league coaches ( as recently confirmed by taking 14 debutants to a series win in the State of Origin this year against raging favourites) had this exact philosophy. A player is taken for his strengths, so he works to make those strengths stronger. Good tackler? He will make you a great tackler. Fast runner? Train to get faster (or dare I say it more swerveable) etc. That's not to say work cant be done to limit deficiencies but the overall idea is to work with a players strengths to make them stronger.
It works.
