From the ISFP description on best fit:
Probably I’m the happiest when things are just a little different everyday. I don’t want to commit to any particular way to be. I want to be able to be a lot of ways.
Maybe that's why I've changed my type at least six times now? And up to the last few days I was confident I was an 'N'. A lot of it, as well, has to do with the fact that I am intelligent, was awarded academic scholarships to high school and college, I -gasp- love to read, etc. You get the impression from reading these forums and the type descriptions that the SP types are numbskulls who spend all day fooling around. Oh wait, I do that... but I'm not an idiot. But yes, I would rather go to a concert where I can experience the music, not to mention get drunk (although every time afterwards I reprimand myself to stick to the three drink rule... but then a new situation arrives and I want it! And why not? It's fun!) than sit around and think up theories.
Life is for living, not for analyzing, in my opinion. Although I can 'play' in that realm as well.
