Inflexible and Stubborn - The problem with being so fixated on what works is that ESTJs too often dismiss what might work better. Everything is opinion until proven, and ESTJ personalities are reluctant to trust an opinion long enough for it to have that chance.
Uncomfortable with Unconventional Situations - ESTJs are strong adherents to tradition and when suddenly forced to try unvetted solutions, they become uncomfortable and stressed. New ideas suggest that their methods weren't good enough, and abandoning what has always worked before in favor of something that may yet fail risks their image of reliability.
Judgmental - ESTJs have strong convictions about what is right, wrong, and socially acceptable. ESTJs' compulsion to create order often extends to all things and everyone, ignoring the possibility that there are two right ways to get things done. ESTJs do not hesitate to let these "deviants" know what they think, considering it their duty to set things right.
Too Focused on Social Status - ESTJs take pride in the respect of their friends, colleagues and community and while difficult to admit, are very concerned with public opinion. ESTJs (especially Turbulent ones) can get so caught up in meeting others' expectations that they fail to address their own needs.
Difficult to Relax - This need for respect fosters a need to maintain their dignity, which can make it difficult to cut loose and relax for risk of looking the fool, even in good fun.
Difficulty Expressing Emotion - This is all evidence of ESTJs' greatest weakness: expressing emotions and feeling empathy. People with the ESTJ personality type get so caught up in the facts and most effective methods that they forget to think of what makes others happy, or of their sensitivity. A detour can be breathtakingly beautiful, a joy for the family, but ESTJs may only see the consequence of arriving at their destination an hour late, hurting their loved ones by rejecting the notion too harshly.
