Just catching up on my feed list and read this article on Thinkvitamin. Dividing people into 2 categories and summing them up as positive or negative. Either looking for opportunity and getting on with it or finding problems and reasons not to do something.
It has provoked a lot of comment as would be expected with such a statement, particularly from those who point out that you can't contradict this as you would be considered a troll (very true).
I think Ryan makes a valid point though. If you can try to keep on the positive side you are more liklely to get something done. He also acknowledges that we all have a bit of both in us, and it is important to have the occasional negative as it is often the catalyst for progression.
