People these days use the word "dopamine" as if it was something they snort lines of: "I got a hit of dopamine when…". Yes, I know you think this makes you sound educated, but actually you're revealing that you barely know what dopamine is or does. Heightened dopaminergic activity is neither necessary nor sufficient for pleasure; ask all the Parkinson's patients on L-DOPA if you don't believe me. It would be more honest to say that you got a hit of one of the four humors, because then the casual listener would more easily apprehend that you're talking out of your tuchus.
While you're at it, stop using the word "DNA" to mean "character". You're not misinforming people about physiology with that one, but it's a no less buffoonish abuse of a scientific term.
