Hi, as an ISFP I like to leave things open. I have a hard time making final decisions about external things. I just go with the flow. But sometimes when I really need to make a final decision and make things happen, I can apply logics to the situation. This is probably the inferior Te working. If I am not pleased with the way things are going I ask myself: "Do I like the way things are?" Answer: "No!" Solution: You have to do something about it. I know it seems really simple but it's a way to force myself into some J behaviour.
It's fascinating how hard it can be to use simple logics in making personal decisions. At least for an ISFP.
Do other ISFP:s have the same experiences? What about other types? Have you noticed your inferior function in action??
