Trust me, you don't want that. When I was a kid, dealing with the grief of losing my mother and the pain of being bullied, I tried to follow Spock's example and suppress my emotions, but I ended up being more like the Incredible Hulk, since without a healthy release the emotions just built up until they burst out of me in dysfunctional ways. I came to accept, around the same time Spock did in ST:TMP (and maybe in part because of that), that emotion is natural and needs to be accepted, that fighting it just does more harm.
Emotion cannot be eliminated. Without emotion, there is no motive to make any decision or undertake any action. Neurological studies have shown that even the most detached intellectual tasks, like solving math and logic problems, engage the emotional centers of the brain, because we feel a need to find a solution or an affinity for a correct answer. Feeling is an inseparable part of thinking. Even the attempt to deny or avoid feeling is motivated by an emotion, the desire to avoid pain.
But emotion can be managed and directed. Once you accept it as part of yourself, that gives you the ability to take control of it -- or simply to acknowledge it and move beyond it, rather than letting it oppress you. Think in terms of martial arts -- it's about letting the energy flow through you and redirecting it smoothly in the direction you want, rather than trying to struggle against it and hurting yourself in the process. Indeed, martial arts or yoga can be excellent for calming the mind and learning emotional discipline.
