Atomic Habits 87

The strength of genetics is also their weakness. Genes cannot be easily changed, which means they provide a powerful advantage in favorable circumstances and a serious disadvantage in unfavorable circumstances. If you want to dunk a basketball, being seven feet tall is very useful. If you want to perform a gymnastics routine, being seven feet tall is a great hindrance. Our environment determines the suitability of our genes and the utility of our natural talents. When our environment changes, so do the qualities that determine success. This is true not just for physical characteristics but for mental ones as well. I’m smart if you ask me about habits and human behavior; not so much when it comes to knitting, rocket propulsion, or guitar chords. Competence is highly dependent on context. The people at the top of any competitive field are not only well trained, they are also well suited to the task. And this is why, if you want to be truly great, selecting the right place to focus is crucial. In short: genes do not determine your destiny. They determine your areas of opportunity. As physician Gabor Mate notes, “Genes can predispose, but they don’t predetermine.” The areas where you are genetically predisposed to success are the areas where habits are more likely to be satisfying. The key is to direct your effort toward areas that both excite you and match your natural skills, to align your ambition with your ability. The obvious question is, “How do I figure out where the odds are in my favor? How do I identify the opportunities and habits that are right for me?” The first place we will look for an answer is by understanding your personality. HOW YOUR PERSONALITY INFLUENCES YOUR HABITS Your genes are operating beneath the surface of every habit. Indeed, beneath the surface of every behavior. Genes have been shown to influence everything from the number of hours you spend watching television to your likelihood to marry or divorce to your tendency to get addicted to drugs, alcohol, or nicotine. There’s a strong genetic component to how obedient or rebellious you are when facing authority, how vulnerable or resistant you are to stressful events, how proactive or reactive you tend to be, and even how captivated or bored you feel during sensory experiences like attending a concert. As Robert Plomin, a behavioral geneticist at King’s College in London, told me, “It is now at the point where we have stopped testing to see if traits have a genetic component because we literally can’t find a single one that isn’t influenced by our genes.”
