Reckless people is the answer. Not thoughtless, but reckless people who care. The reckless bold people who are not afraid to do things their way. Different way. And they don’t usually care what everybody else thinks and says.
Guess what other trait these people have in common. They usually are incredibly physically fit, strong and healthy. Yes, the fragile or overweight pale geek sitting behind his computer and creating breakthrough software is a big fat myth.
In consequence of their great physical fitness, these people have a lot of energy, they are restless, and that creates huge amount of healthy self confidence. Of course, you find a bunch of egomaniacs between them too, but that has more to do with a character and less with physical fitness.
If you put intelligence, passion, creativity and great physical fitness together, it will create a person with huge amount of energy, that is not afraid to do neccessarry scary things, who proceeds recklesly and boldly and that changes the world.
Are you by nature afraid? Do you worry a lot? Do you feel tired often? Can you make a decision and stick with it even if everybody disagrees? If yes and no, maybe you should get yourself in a better physical shape to fix that. Just a thought.
