I'm pretty sure I'm a - type, except that according to this page http://socionics.us/theory/ext_int.shtml I look more like an Extrotim.

For example :

- My natural voice is usually loud, even more than most extrotims. Many people told me to lower my voice. Many Introtims have a loud voice, and not only those stupid LSI's.

- My optimal level of arousal is quite high. I feel bored by lack of stimulation most of the time.

- I don't really think of the past. I'm really an impatient dude. But this trait does correlate to Introtimness, as most S- people are Introtims.

- I'm a bad listener. I often feel like I'm deaf, and I often ask others to repeat what they said.
