Reward pushes us around
In a sense, you are the play thing of chemical "gods"
What guides what we do? Countless choices of actions,

computed at the micro level of my neurons?
Fluctuates pretty much all the time
guiding us throughout our lives

Cocaine are mediated through the same mechanism which have evolved for highly functions. We do because we get a chemical kick out of it. Important part of our pleasure and reward responses. Stating point for the stimulation and release of dopamine. Further away from spinal cord, newer evolutionary regions. Vta: feeds dopamine release to areas in the diagram. Amygdala: threat; detecting the significance of a situation.
