I have an ENTJ dad who is a great businessman. Sharp, shrewd, organized, detail-oriented. I've been helping him on a business deal over the last few weeks.
So we had an argument recently. He says one of my (and ENFPs in general) best qualities is believing in the best in people, especially strangers. But when it comes to business, it's a bad quality to have. The argument was whether our potential business partner was going to try and screw us over.
I really believed, "Why would he? We all stand to win by cooperating. By screwing us over, his 'win' would be much much smaller than if we all cooperated."
Lo and behold, my dad's suspicions turned out to be right.
Jeezus, it made be really doubt my ability to be a business executive/leader one day.
It seems you really need to have that xNTJ function in order to make smart business decisions. My NF is fucking me so hard...looking back now, I still have no idea why I went to bat so hard for our this other guy. That was so dumb of me...
