1 and 2: The first two functions are the functions that are the most natural and easy to use and that one is most comfortable using. It seems that the 1st function is what you automatically are, and the 2nd function is what you automatically do. It also seems that extensive use of the 2nd function exhausts a person, while the 1st function doesn't. However, when the 1st function is used and the second function is not, a person may not feel stimulated.
3: You feel like it is expected of you and sometimes resent this, especially if the first two functions are not being rewarded. It seems it can be somewhat of a sore spot, something which causes frustration. You use your 3rd function because you don't feel you can get along in the world well unless you do. The reason you feel we're supposed to use 3 is because 5 is weak.
3 and 4: I think the difference between the 3rd and 4th function is that with the 3rd, you feel you should use the function. It isn't generally a very strong function, but it's not the weakest because it's something we make a conscious effort to use. The 4th function is also something that is a sore spot, but you do not feel that it is reasonable for others to expect us to use it and generally see no reason that you should have to.
5: You don't realize that you're not doing this because you use the 3rd function in it's place. You're not sensitive about this function being weak. You don’t realize you need help with this function, but others do.
6: You are sensitive about this function because you like to think it is strong, and you are quite responsive when others use it or make you feel that you're doing a good job using it.
7: This something you unconsciously pay attention to in others and don't use unless provoked, and then you use it aggressively.
8: you inspire others to use but don't really notice.
