As an ENFJ my stacking's FeNiSeTi.
I recently started consciously trying to get more in touch with my Ti and I noticed how automatically my Se has kicked in.
My question is: From my understanding your functions serve your dominant function. But how is the relationship with the 3rd and 4th one? Are you dependent on a well functioning 3rd function for the 4th to develop, be trained effectively, engaged etc. or are they not necessarily that much related at all and it all comes down to your two main functions?

Though Jung himself didn't say anything about it, both MBTI and especially Socionics believe that functions work in pairs. After all, consider how different an INFP and an INTP use their Ne. In terms of Socionics, these pairs are known as blocks, and MBTI generally just refers to them by their pairs. In this case, you are trying to activate your Super-Id block. So it makes sense that when activating Ti, Se would also activate because they work together!
