The 4's imagination is not well developed, and his views are usually narrow-minded and conventional. The 4 tends to be religious without questioning established doctrine, preferring to parrot the beliefs of his peers, feeling safe and secure in the predictable, unchanging nature of a tight discipline. More than any other number except perhaps the 7, 4s are found in the charts of monks, priests and other religious leaders. Many also become excellent managers and organizers, and it is not at all uncommon to find a 4 in the upper echelons of business and government. The 4 will work hard and can be driven to reach the top of his profession, but in striving to reach the top he usually finds that his greatest obstacle is himself: his lack of social skills, his inability to relate to the mundane issues of his co-workers and his lack of intuition.
The 4 doesn't like to make waves, but values his moral convictions and will not back down when convinced that he is doing "the right thing." However, he can also be intolerant and, when faced with people from other cultures, countries or races, his insecurity can turn him into a cruel bigot. Many 4s choose a career in the military, where their obedient, disciplined nature is right at home. They especially thrive when they are assigned duties that include administrative and organizational work.
As with any number, there are some contradicting traits within the 4. For instance, while he is not particularly social or fun-loving, the 4 sometimes reveals an entertainingly dry sense of humor. Further, although he is a strict and disciplined parent, the 4 is also extremely devoted and will walk through fire to get his kids what they need.
My description of the 4 is, not surprisingly, almost the exact opposite of my description of the 3. This is to be expected, as every number is, in important ways, a counterpoint to the one that directly precedes it. The 2 is the polar opposite of the 1, the 3 displays traits that are directly opposed to those of the 2, and so forth. And of course the differences between the 5 and the 4 are like night and day!
