Just a warning: we have to be aware that we tend to project stereotypes into people without being aware of it. For example its a good idea to ask ourselves if we think hes ESTP simply people because he corresponds to an ESTP stereotype, or if we have objective criteria like we do when we type ourselves. Im not blaming anyone in particular just warning.

I dont know what his type is, he could very well be ESTP, but there is no real arguemant so far as to why, except that his (or at leats his appearance of) wilfullness could suggest .
