I want to master pain and pleasure.

I want to master pain and pleasure; happiness and sorrow. I want a direct control of my emotions. The same way I can control my muscle movements; like my breathing.

If that's not a possibility, then alternatively, I desire constant happiness or freedom from painful emotions/distress/worry.

Ideally, I want to get rid of negative emotions completely.

How can one achieve this?

Additional Information:

Emotional experience is a ubiquitous component of the stream of consciousness. The emotions motivating the direction of conscious attention, partly constitutive of 'what it's like' to experience anything. But all phenomenal consciousness must be emotionally motivated; thus the 'what it's like' aspect of a phenomenal experience is inseparable from the emotions that permeate it. E.g., visual cortex activation is unconscious of red unless the emotional midbrain, limbic system, and anterior cingulate motivatedly "look for" a red object.

Your experience of so-called reality is filtered through your memories, giving your experience a spin, adding meaning. We’re constantly resonating with what we already know to be true. Everything that you feel is filtered along a gradient of past experience and memory that’s stored in your receptors. What you experience as reality is your story of what happened.
