The INFJ is honest and trustworthy, exuding integrity and sensitivity, and have a single-mindedness which will see them plan, organise and work tirelessly to achieve their goals. In this lofty pursuit they may be difficult to deflect from their chosen course of action, not as with the ESTJ from a desire to ‘get it done,’ but from the standpoint of ‘it’ being a worthwhile cause and having been arrived at by tortuous deliberation, therefore it must be right and the INFJ will always do what is right. As their focus is so much on ‘the bigger picture,’ and their primary drivers their values and the desire to ‘do good,’ sometimes the INFJ will find that reality or factual details get in the way of their lofty ideals, their serious schemes and their dreams of a better tomorrow. ‘Facts’ which do not support their ideas or which get in the way of the grand scheme may be ignored in their aspirational desire to reach Nirvana. INFJs value harmony and authenticity and they will bring an incredible work ethic and duty of care to anything they perceive as worthwhile and they will be unlikely to work on any project they felt was not worthwhile. They combine an idealism with a structured approach and tireless work and thus can effect real, lasting, change in the organisations they work in. The INFJ may not be the most easy to know but they will want to support and nurture others.

Although caring, kindly and amenable the INFJ has a very strong set of values, which, if transgressed, can make them crusading, vocal and extremely stubborn. Their single-mindedness can be such a positive and energising trait, creating genuine breakthroughs and coming up with such creativity. However they can struggle when their ideas are not workable and may neglect to paint in the brutal facts of reality into their lofty ideals. The INFJ also often takes on too much and this can see them become overwhelmed and de-energised and withdraw to bring their energy levels back up. Their idealism also means that at times the INFJ may be unrealistic about timescales and how much they have taken on, becoming ‘snow-blind’ to problems as they carry on regardless as their mission is so all consuming and important to them. At such times the INFJ sometimes struggles to remain open to other people’s ideas as they are focused so much on the goal, which is of course linked to their ideal. Although they can be crusading on issues that are important to them the INFJ does not generally like conflict and may simply withdraw when the situation becomes tense or loud or where there are multiple, competing viewpoints as the INFJ is intensely introverted and so they prefer to speak when they have a clear purpose and a point to the discussion.
