Insensitive - Feelings and emotions come second to facts and "reality" for ESTPs. Emotionally charged situations are awkward, uncomfortable affairs, and ESTPs' blunt honesty doesn't help here. These personalities often have a lot of trouble acknowledging and expressing their own feelings as well.
Impatient - ESTPs move at their own pace to keep themselves excited. Slowing down because someone else "doesn't get it" or having to stay focused on a single detail for too long is extremely challenging for ESTPs.
Risk-prone - This impatience can lead ESTPs to push into uncharted territory without thinking of the long-term consequences. ESTP personalities sometimes intentionally combat boredom with extra risk.
Unstructured - ESTPs see an opportunity – to fix a problem, to advance, to have fun – and seize the moment, often ignoring rules and social expectations in the process. This may get things done, but it can create unexpected social fallout.
May Miss the Bigger Picture - Living in the moment can cause ESTPs to miss the forest for the trees. People with this personality type love to solve problems here and now, perhaps too much. All parts of a project can be perfect, but the project will still fail if those parts do not fit together.
Defiant - ESTPs won't be boxed in. Repetition, hardline rules, sitting quietly while they are lectured at – this isn't how ESTPs live their lives. They are action-oriented and hands-on. Environments like school and much entry-level work can be so tedious that they're intolerable, requiring extraordinary effort from ESTPs to stay focused long enough to get to freer positions.
