MBTI the end all be all?

Hi,

I was recently exposed to the MBTI tests.

I scored ENFP on one test and ESTP on another, though I believe ENFP is a more accurate description of my personality.

My question is: is the "official" description of ENFP, or any other one for that matter, the end all be all accurate description?

Example: I am getting married, does that mean I will get bored easily? Do ENFP's have a higher divorce rate?

Example #2: I want to become a pilot - I always have and I am considering flight training. The job is routine oriented, but I love flying planes.

Thanks!
