You are a Shark (ISTP)!
The fiercest of all the types, you have an aggressive mentality and hypercompetitiveness that sometimes strikes fear into the hearts of the more passive types. Sometimes they just perceive you as a jerk. You are blunt and straightforward, and place a high value on skill. People are either good at things or they’re not, and you take great pride in your ability to master a specific craft, as you feel it is much more a product of your discipline and dedication than any raw talent.
