I've read general summaries of healthy/unhealthy versions of the 16 types and have my own speculations about how those can be demonstrated by specific behaviors in real life, but I'm curious to see how other people have experienced healthy versions of any of the 16 types-- specifically, what behaviors have shown them manifesting their functions in healthy ways.
If you've encountered people in your life who are productive, likable, and are able to utilize their type's personal qualities in ways that make them wise and developed, what behaviors have demonstrated a healthy use of their functions?
INFP = A friend of mine is a senior in college and is deciding what to do after she graduates. Her strong sense of self-knowledge about her personal tastes, values, and preferences allows her to understand how all the myriad of jobs out there could be ideal for her, but she has learned to be accepting of her limits in the world, being at peace with the fact that she can't always get what she wants, so that she isn't blindly pursuing something she likes but realistically cannot achieve (healthy use of dominant Fi to discern all the options noticed from the use of auxiliary Ne). Personal experience with some familiar job tasks (additional help from tertiary Si) also helps her understand what she personally values in a job that she has an appropriate chance of getting. When she's sure of what she wants, use of inferior Te helps her ensure that she can decide on some job options and pursue employment successfully. Use of any of the shadow functions are also helpful to her-- for example, she tends to seek validation from others and is always aware of what her friends will feel about her choices, so she has learned to use her shadow Fe to deepen her understanding of her Fi, understanding others' preferences and why she would want to be different or similar to them.
(It would be great to have something like this for all 16 types, but feel free to share different examples of the same type if you want!)
