Enjoyment is personal, it is about you. You feel happy or you get disappointed, because it is about your emotions and it is a feeling of self.
lets take some scenarios of mine for illustration.
I shout and get thrilled when I go on a roller coaster (does not matter who sits besides me).
I get scared to death when I go to a haunted house, even when I stick behind my wife.
That's me and those are my feeling and that's how I react.
Science relates it to the hormones that makes you thrilled and the activities that get those hormones out! Again it is all about you; it is all about me.
One's feeling defines him or her. If you know the feelings then you know them. This is highly used in the business world by touching the ego. All deals go with ego, be it small or large. Again it is about feelings and it defines you.
So, the practices of NLP become critical, but being humans, the diversity is huge as we evolve!
Next we shall talk about identity - which is worldly.
