The Genetics of Happiness 129
Hugh Pickens writes "Studies comparing identical twins with non-identical twins have helped to establish the heritability of many aspects of behavior. Recent work suggests that about one third of the variation in people's happiness is heritable. Jan-Emmanuel De Neve has taken the study a step further, picking a popular suspect — the gene that encodes the serotonin-transporter protein, a molecule that shuffles a brain messenger called serotonin through cell membranes — and examined how variants of the 5-HTT gene affect levels of happiness. The serotonin-transporter gene comes in two functional variants—long and short and people have two versions (known as alleles) of each gene, one from each parent. After examining genetic data from more than 2,500 participants in the National Longitudinal Study of Adolescent Health, De Neve found that people with one long allele were 8% more likely than those with none to describe themselves as very satisfied with life and those with two long alleles were 17% more likely of describing themselves as very satisfied. Interestingly enough, there is a notable variation across races with Asian Americans in the sample having on average 0.69 long genes, white Americans with 1.12, and black Americans with 1.47. 'It has long been suspected that this gene plays a role in mental health but this is the first study to show that it is instrumental in shaping our individual happiness levels (PDF),' writes De Neve. 'This finding helps to explain why we each have a unique baseline level of happiness and why some people tend to be naturally happier than others, and that's in no small part due to our individual genetic make-up.'"

Baseline happiness can arguably be negatively correlated to competitiveness, drive and success. You are naturally happy, so you don't worry about making things better for yourself or your children, you just go with the flow because things are pretty good the way they are.

Or not, because people who are depressed feel like it doesn't matter what they do, life's going to suck anyways. They may also respond to their constant unhappiness by looking for artificial mood boosters, which can lead to alcoholism or drug use. They frequently also fail to recognize the value of their accomplishments. By contrast, a happier person is more likely to trigger their brain's reward mechanisms when they do something productive, so they're likely to repeat the behavior.
And it's also worth noting that it's unclear to what degree "drive" and "competitiveness" has to do with "success": The best predictor of a person's level of educational attainment is their parents' educational attainment. The best predictor of athletic success is genetic advantages like height, eyesight, and weight. Artistic success has a fair amount to do with whether a kid's artistic efforts were encouraged or discouraged early on. Most of the really wealthy people in the US inherited a significant amount (Paul Allen is the exception on this front, not the rule).

I believe this might also be the case with non-SSRI anti-depressants like Wellbutrin (which is really more like a serotonin production booster than something that keeps it from being removed from the system). I think this is a very good point and I'm glad you mentioned it.
