Are you Single-minded?

While the bulk of my posts have focused on developments in the Pharmaceutical industry, I also like to post occasionally on topics related to Career Development.
And along those lines, there is an interesting post here.

We often hear it touted that we should all strive to be well-rounded....that we should work to improve our weaknesses....that we should strive for a balanced life.

David Rendall does not agree with that philosophy. He writes:

"While you are busy diffusing your time and energy broadly in an effort to improve in a variety of different areas, someone else is obsessively developing their strengths and flaunting their weaknesses. They aren't allowing their weaknesses to distract them from focusing on the areas in which they have the greatest potential.

If you want to win, in your career or your business, you need to be singleminded. Don't let your weaknesses and the goal of being well-rounded keep you from a maniacal focus on improving your strengths."

I think his point is valid....Being successful in any one area requires sacrifice....including possibly giving up the pursuit of success in other endeavors.....
