Sure, but to give to let an intp out in the world with the advice "develop your Ne" wont help him at all either. I know I didnt find the right words to tell him what to do, but thats basically because I dont know him. Therefore I could only say: never say "develop your Ne", cause then people will think you are a freak
Yeah, but you develop conscious functions by using them.
And different activities require uses of different functions. (Sure, some are more open-ended than others, like surfing the internet, but that doesn't mean they all are. Kind of like... solving a physics problem requires a strong degree of analytical thinking.)
And since everyone is different, everyone develops lesser functions in a different way.
Asking a question like the OP may not be very helpful to you, but for those with a dominant Ti, sorting these activities through function analysis helps confirm their importance by backing them with reasoning.
Personally. Going through the day thinking things like, "today I'm going to develop Ne!" has definitely helped make me less of a social freak.
Wolfy started a thread here referencing to Dario Nardi's book. There is a quick quiz at the beginning of each chapter on functions. You can determine how developed the function is. From that it gives tips on how to develop the function from that point. I have heard nothing but good things about the book, but I have not been able to find it locally and do not want to pay the shipping charges.
