The buzz is not related to the act of trading itself, at all.
The buzz is derived from having mastered all of the topic, including mastering yourself, and from the intellectual satisfaction that this yields, and from being able to replicate success, on command,
at will, and of being able to choose to participate or abstain.
The buzz is derived from the sure knowledge that you have attained total mastery, a knowledge that is reinforced by results.
All of this takes a long time to perfect.
