Once upon a time, I thought I understood Fi. Now that I know about process/result and +/-, I'm not so sure. How does one actually increase Fi? I don't get it.

Fi is drive, right? I can see you increasing hormones to increase Fi. And if one hormone surpasses the intensity of another, then its drive dominates over that other. Is this Fi?

Then, where does ethics come in? Really, there must be more to Fi than just hormones and drives.
