Left brain vs right brain

I found this picture by Alix de La Tour du Pin on a french blog about entrepreneurship (here).
This is indeed a really good mashup of what we are all made of : rigor and creativity. As an engineer I tend to have my left brain side take over my full body, but it clearly is really important to let both sides of it show up every once in a while.
Of course anyone will tell you that women have a more developed right brain side, hence their enhance creativity, and our relative incomprehension of their way of working (easy shot granted :-D).
Anyhow, reading about entrepreneurship and speaking with colleagues I find it really important to manage the both sides of your brain efficiently. The left side will hep you manage your work and keep things on track over time. However the right side will help you find the one path to success as well as the necessary envy to get through the day happily and make sure that you keep your work experience a fun and interesting one. Therefore it should be every manager’s duty to encourage his team to let the fun come at the table once in a while in order to make sure that the work can be done nicely and efficiently. And of course this should be the prime role of every entrepreneur out there, not only to make sure that his company always figures out the best ideas before the other ones, but also to make sure that his team (however big or small it is) remains happy and efficient at work.

And you, what’s your take on rigor vs creativity ?
