Took the MBTI test online just now and my personality is ISTJ. That is an almost exact opposite from what I got about 2 years ago (INFP). Was it the (happy & unhappy) experiences I had that changed my personality? Was it the people I met? If yes, then which experience and people affected me? I hope it's a good change though.
Here's what I got from the internet and it's almost entirely true.
Introversion (I): How you direct your energy and relate to the world around you. ISTJs prefer spending time along or with small groups of close friends.
Sensing (S): How you take in information from the environment. ISTJs prefer to focus on the details rather than thinking about abstract information.
Thinking (T): How you make decisions. ISTJs make decisions based on logic and objective data rather than personal feelings.
Judging (J): How you orient yourself to the outside world. ISTJs are planners; they like to carefully plan things out well in advance.
Some of the main characteristics of the ISTJ personality include:Focused on details and facts
Realistic
Interested in the present more than the future
Observant, but slightly subjective
Interested in the internal world
Logical and practical
Orderly and organized
ISTJs enjoy an orderly life. They like things to be well-organized and pay a great deal of attention to detail. When things are in disarray, people with this personality type may find themselves unable to rest until they have set everything straight and the work has been completed.
Because of this need for order, they tend to do better in learning and work environments that have clearly defined schedules, clear-cut assignments and a strong focus on the task at hand. When learning new things, ISTJs do best when the material is something they view as useful with real-world applications. Concrete, factual information appeals to ISTJs, while theoretical and abstract information has little value unless they can see some type of practical use for it. While they may exert tremendous energy into projects they see has valuable, they will avoid wasting time and energy on things that they view as useless or unpractical.
ISTJs are both responsible and realistic. They take a logical approach to achieving goals and completing projects and are able to work at a steady pace toward accomplishing these tasks. They are able to ignore distractions in order to focus on the task at hand and are often described as dependable and trustworthy.ISTJs also place a great deal of emphasis on traditions and laws. They prefer to follow rules and procedures that have previously been established. In some cases, ISTJs can seem rigid and unyielding in their desire to maintain structure.
People with this personality type are usually very loyal and devoted to family and friends, but may struggle to understand their own emotions and the feelings of others. They can be quite reserved and sometimes fail to pick up on the emotional signals given by other people. However, once they are close to a person and develop an understanding of that person's feelings and needs, they will expend a great deal of effort toward supporting those needs.
