Personality and self-assessment research is a good exercise to go through when a bit of guidance is required. Bear in mind, they definitely won't be able to tell you who you will be and what you'll be best at. This can only work out.
But, their advantage was that they could shed some light on the best course or route. Such assessments could bring something you have overlooked to light. Unfortunately, I was tied between two types of personality when I took this test.
A person with more than one type of personality (this doesn't make you a crazy person) gives you different perspectives that show you can illustrate more than one way of thinking.
