So I was reading this thread (INFP profile - INTJ Forum) and it gave a very in-depth description of an INFP. Reading about Fi and Ne was very interesting but what really hit me was reading about the underdeveloped Te and somewhat underdeveloped Si functions. This really hit home with me because it is very difficult for me to make big social decisions as my Fi usually wants me to have the best time even when there are many options available (such as deciding who to hang out with, which party to go to, etc.).
The OP also talks about the best way to cultivate Te and Si so that the INFP can realize that tough-minded decisions are often the best way to go and everything in the world is not the result of "personal will" (middle of the first paragraph). He/she goes on to say that the most effective and natural way for an INFP to increase his Te is to let the Si develop naturally.
My question to you guys is how do you do this?
