"You do it for the highs, when you're totally engrossed and everything's flowing and whatever you want, you get. It's like magic. That's why you play the game. That's what it's for. That's why you work"

This quote by Greg Rusedski speaks with the delight and complete satisfaction that originates from engaging in a meaningful activity. He is referring to the sensation of being "completely immersed" in something, when whatever is going right and you have the ability to achieve the preferred result. This sensation is typically described as "magic", and it is this feeling that encourages us to continue to engage in the activity. It is why we play the game, why we work, and why we strive to reach our objectives. It is the feeling of achievement and satisfaction that keeps us going, and it is this feeling that makes the effort beneficial.
