Do I need to develop impressionability? Actors, artists, poets — this is useful and necessary, they earn money on this. For other people who are far from the art business, impressionability is rather harmful, because it knocks down the work of the mind. Impressibility, if you already have it, can be used — impressionable women with their sincere experiences can have a killer effect on gullible men, but if you are not naturally impressionable, then just be happy for yourself.
Impressibility and metaphorical perception
On the other hand, metaphorical perception is close to impressionability: figurative perception, based on the similarity rather emotional, sensual, rather than strictly logical. Metaphorical perception is very useful to develop. See Development of Metaphorical Perception.
Impression and empathy
Close to impressionability and empathy — a direct feeling of the state of another person. Developing empathy is extremely beneficial. See Development of Empathy
