Conversely I think too much introspection can also cause confusion when trying to identify functions through analysis paralysis.Introspection isn't easy for everyone.
You should just live, and observe how you react to things. Once you understood functions well, you'll be able to notice them everywhere (it's quite odd). Those patterns are just present in everything. Self-reflexion needs some time, because you can't base your judgment on your actual mood. Just live normally, and watch externally who you are.
