Strong vs. weak is largely a matter of confidence. Sometimes the strong functions can get too confident. For instance, the other day I had to go get some vaccines. I didn't make any preparation until the actual day of the appointment, scheduled for 10:30am. With only 4 hours of sleep I get up an hour and a half before the appointment and
-look up the directions to the clinic
-call my friend to get his university password so I could use his printing pages
-run/walk to a university computer to print off the insurance information
-go to the bus stop (ended up waiting for 15 min as the bus was late)
-get off at the right stop, never having taken the bus route before
-get on another bus
-again get off at the right stop and walk a block or two to the clinic
I ended up getting there with only a couple minutes to spare. Any one of a number of tiny things could have gone wrong - I could have slept through my alarm, the bus could have been too late to make the transfer, etc. Someone with weaker might have prepared for these a little beforehand, but I think the fact that I have strong makes me especially likely to trust myself to do everything super-last-minute and just assume that everything will go according to plan. It also probably has something to do with not valuing .
Another thing about confidence is that often one may appear to be admitting weakness in a certain area. types seem especially likely to admit being afraid of something - but I think this is not an admission of weakness given the right mentality. Often in an argument I'll say "I don't understand." From my point of view, I am not admitting fault, I am criticizing the other person's clarity of expression ().
