I know exactly this personality. They are great people one on one. That's why they are good at their jobs but they also have a mental block and ultimately they are making sure their own base is covered while promoting the dismantling of others. When I talk to these guys at parties they avoid me for about a year and then after about 5 years close to retirement they open up.

It's funny.

It's also really bad for their spiritual progress. Alas they serve God dragging down thy demented and spiritually bankrupt for a Fiat paycheck and a fancy tombstone. Conversely the intellectual drunk doesn't take care of anyone, including himself and he just gets a state funded funeral in the trash heap. This is why the means between extremes is so important.

I'm the intellectual drunk and it's a terrible place to be until one surrenders to the Almighty. Then things get very nice.
