Interestingly people vary much in emotional intensity under which their mind works best. I function best in a relaxed, dreamy and happy state. When I am unhappy or under pressure, my thinking does not work as well. I also enjoy thinking in a team. I can easily pick up ideas of others and develop them further. I can utilize energy of my team mates for solving problems for them. On the other hand I find it difficult to think in the presence of negativity, under pressure and in unhappy crowd. This is frequent in large cities; it is hard to escape negative energies.
I found that some people have similar qualities as I. I also find that some people work best in conflict situations. They thrive on conflict. They create a conflict and psychological tension because that helps their thinking process. These people are good warriors - in tough situations they perform best.
Since there is much diversity on Earth and since Earth is conducive to diversity, you will find a large variety of thinking traits among humans. This diversity is also helping much our evolution. We evolve pretty fast.
