Enjoyment is pretty straight forward: this moment feels great! That’s awesome! Wow, look at that! This is fun! This feels so pleasurable!
Appreciation I was always a bit confused by. I guess appreciation is recognizing how one’s enjoyment is valuable, or worthwhile. Is appreciation comparative to other less enjoyable states of being, or is one so focused on the enjoyment of the moment that appreciation is focused on the benefit of the sensuous experience?
