Inner drivers

Be perfect!

People with this driver have to do everything especially thoroughly. Perfection is the main goal, no matter what the cost. Because they work flawlessly, they hope for recognition. They are often in the process of justifying themselves. And mention concerns and possible criticism in advance.

41 / 50

Be strong!

Get it right!

People with this driver have learned not to show weakness. They convey a controlled attitude, assertiveness and perseverance to the outside world. At the same time, they hide their feelings and appear reserved to stoic.

People with this "do it right" driver like to feel responsible for others. They want the other person to feel good and are primarily concerned with the question of what the other person might want and what might be good for him.

36 / 50

34 / 50

Hurry up!

Make an effort!

People with this driver are never really present. They always have to do everything immediately and quickly, preferably, several things at the same time. They are always in a hurry, sitting there quietly, doing nothing is just as impossible as concentrated work.

People with this driver know: Anyone who works so hard is conscientious and diligent. But they are also under a lot of pressure to perform. Successes that are not based on hard effort don't count. If something doesn't work out, they have to work even harder. They live in constant fear that others could be better. The only thing that helps is even more effort.
