Sensitive - ESFPs (especially Turbulent ones) are strongly emotional, and very vulnerable to criticism – they can feel like they've been backed into a corner, sometimes reacting badly. This is probably ESFPs' greatest weakness, because it makes it so hard to address any other weaknesses brought to light.
Conflict-Averse - ESFPs sometimes ignore and avoid conflict entirely. They tend to say and do what's needed to get out of such situations, then move on to something more fun.
Easily Bored - Without constant excitement, ESFPs find ways to create it themselves. Risky behavior, self-indulgence, and the pleasures of the moment over long-term plans are all things ESFPs get into a little too often.
Poor Long-Term Planners - In fact, ESFP personalities rarely make detailed plans for the future. To them, things come as they come, and they rarely bother with taking the time to lay out steps and consequences, with the belief that they could change at any moment – even with things that can be planned.
Unfocused - Anything that requires long-term dedication and focus is a particular challenge for ESFPs. In academics, dense, unchanging subjects like Classic Literature are much more difficult than more dynamic, relatable subjects like psychology. The trick for ESFPs is to find day-to-day joy in broader goals, and to tough it out with those tedious things that must be done.
