INFJ and TI - Is Fi or TI the Way to Go?

I would say that people who've helped me the most. Either were TP or FP types. The TP because they're really coming with, they're able to introduce a model or ask a question that like changes my way of thinking about it. And with the FP types, they're just like very patient and they speak very quietly. But I can think of one, an INFJ teacher that I had. She will just bluntly give feedback sometimes. Every single time she's right. So it's either Fi or TI, I think is a way to reach the TE folks.
