My life as an INFJ (introverted Intuitive Ni; supported by extroverted Feeling Fe) has been a series of "Boom and Bust" cycles. Even as a kid, I would be exhausted by the end of a day at school and would recharge by immersing myself in a good fantasy book for most of the weekend.
Why all this stress? Why are INFJs the most stressed of all personality types? One of the main reasons is that we are so different from most people. Not only does this mean that others find it very difficult to understand INFJs, but also we do not easily fit in society since behavioral expectations are set by the most common personality types. This isn't us. Though there is still a lot of debate over whether extroverts out number introverts, most agree that extroverts range from 50% to 74% of the population. But regardless of the percentage, our society in the United States is dominantly extroverted (compare it to an Introvert culture such as Japan). Also, in our culture Sensors are about 75% of the population and Intutitivies are only 25% of our population. Now consider that of the 25% who are Intutitivies, less than 6% (INFJs 1% and INFPs 4.4%) use their Intuition in an Introverted way supported by Feeling.
