Principles are ways of successfully dealing with reality to get what you want out of life.
Ray Dalio, one of the world’s most successful investors and entrepreneurs, cites principles as his key to success.
Some ways of thinking will serve you well for some purposes and serve you poorly for others. It is highly desirable to understand one's own and others' ways of thinking and their best applications. Some qualities are more suitable for some jobs. For example, you might not want to hire a highly introverted person as a salesman. That's not to say an introvert can't do that job; it's just that a gregarious person is likely to be more satisfied in the role and do a better job.
If you're not naturally good at one type of thinking, it doesn't mean you're precluded from paths that require it. It does, however, require that you either work with someone who has that required way of thinking (which works best) or learn to think differently (which is difficult or even impossible).
On the other hand, sometimes I see people dealing with each other, especially in groups, without regard for these differences. They are like the parable of the blind men touching different parts of an elephant and arguing about what it is. Just think about how much better it would be if people were open-minded enough to realize that none of them have the complete picture. Both people expressing their own views and those considering others' views need to take each other's differences into account. These differences are real, so it's dumb to pretend they don't exist.
