You only understand a topic if you can teach it, use it, prove it, connect it, explain it defend it and read between the lines!
Piaget wryly noted years ago that egocentric persons have only one point of view, theirs!
Unfortunately, most often we can hear this sentence which says, "You just don't understand."
When we truly understand,
- we can explain
- we can interpret
- we can apply
- we have perspective (can see and hear points of view through critical eyes and ears!)
- we can see the big picture
- we can empathize
- have self-knowledge
