According to Myers-Briggs, ESTPs are hands-on learners who live in the moment, seeking the best in life, wanting to share it with their friends. The ESTP is open to situations, able to improvise to bring about desired results. They are active people who want to solve their problems rather than simply discuss them.
According to Keirsey, ESTPs, or "Promoter Artisans", are the most adept among the types at influencing other people. Promoting is the art of maneuvering others to one's position. Concrete in speech and utilitarian in action, they are smooth operators. The ESTP knows everyone who matters and everything there is to do because they are very resourceful, always knowing where the fun and action is. They like to indulge themselves in the finer things in life and to bring other people with them. Their goal in life is to sell themselves and their ideas to others. Dramatic and debonair, they are gifted at earning others' confidence.
According to Keirsey, based on observations of behavior, notable Promoters might include John F. Kennedy, Teddy Roosevelt, Madonna, and Donald Trump. For more examples, see Notable Promoters.
 Other characteristics
According to Myers-Briggs, ISTPs excel at analyzing situations to reach the heart of a problem so that they can swiftly implement a functional repair, making them ideally suited to the field of engineering. Naturally quiet people, they are interested in understanding how systems operate, focusing on efficient operation and structure. They are open to new information and approaches. But contrary to their seemingly detached natures, ISTPs are often capable of humorously insightful observations about the world around them. They can also be closet daredevils who gravitate toward fast-moving or risky hobbies (such as bungee jumping, hang gliding, racing, motorcycling, and parachuting), recreational sports (such as downhill skiing, paintball, ice hockey, and scuba diving), and careers (such as aviation and firefighting).
ISTPs may sometimes seem to act without regard for procedures, directions, protocol, or even their own safety. But while their approach may seem haphazard, it is in fact based on a broad store of knowledge developed over time through action and keen observation. ISTPs enjoy self-sufficiency and take pride in developing their own solutions to problems.
ISTPs are content to let others live according to their own rules, as long as the favor is reciprocated. ISTPs endure reasonable impositions without complaint—but if their "territory" is encroached upon, eroded, or violated, they defend what they view as rightfully theirs.
 Keirsey description
According to Keirsey, Crafter Artisans are masters at using tools of every type—artistic, technological, martial. Although they are introverts, they are authoritarian in their interactions with others and can be forceful at influencing people. They focus on accomplishing tasks efficiently and skillfully.
To master the tool of their interest, ISTPs require a certain degree of seclusion in which to practice. The result is often a virtuosity that other types find difficult to match.
