This is the first factor in raising successful children, according to new research.

If you are an entrepreneur, you are engaged and driven to succeed. If you are a parent and entrepreneur, you are wildly, incredibly busy and drive both you and your children to succeed. This often means running around like a maniac trying to optimize a million factors not only related to your business but a million factors related to your family.

Which diet is best for you kids? what preschool? What a wanderer? Are you reading them enough? discipline them properly, And how much screen time is really too much? Will you accidentally turn them into brats? Or the ones to please the centerless? Or sad study drone?

No wonder so many well-intentioned parents are so jealous. But what if most of the questions that make you lose sleep and sanity don’t really matter? And what if a big question that really has a big impact on whether you kids grow up to be happy and successful rarely pops into your mind?

that’s the dispute a charming new the Atlantic article from data scientists and Author Seth Stephens-Davidowitz, In it he argues that the research is clear: Parents are worrying about a ton of stuff that doesn’t matter and neglecting a factor that really does.

How to increase your child’s future income by 12 percent?

The entire work is worth reading in its entirety, but (spoiler alert) Stephens-Davidowitz’s basic argument is as follows: Rigorous twin studies comparing twins have twins separated at birth by random factors such as administrative adoption decisions. In comparison, parents have found that nighttime stays have little or no effect on children’s life paths.

Whether to breastfeed or bottle feed, screen time limits, how hard it is to push your child academically, or asking them to play an instrument can all have a bearing on the child’s health, test scores, cognitive performance, or other outcomes. has very little effect. (Although one or the other option may be more correlated with raising children in poverty or other difficult circumstances, which obviously matters to their life prospects). Basically, everything you take for granted during pregnancy barely matters.

So should you just aim to do your best and reduce stress? Well yes, maybe. But there is a decision that Stephens-Davidowitz argues that parents think of less. Based on careful research looking at a large trove of IRS data on families with children who have moved between metro areas, science has shown that where you raise your children is comparable to how well they do in life. has a significant impact.

“The best cities can increase a child’s future income by about 12 percent,” writes Stephens-Davidowitz. They were Seattle, Minneapolis, Salt Lake City, Reading, Pennsylvania and Madison, Wisconsin at the time of the study.

Stephens-Davidowitz later in the piece concluded that “putting the different numbers together, I estimate that about 25 percent of the overall effects of a parent – and possibly more – are by that parent on their child.” In other words, this one decision of a parent has a far greater impact than thousands of others.”

It’s not just children.

Not only is the city a quarter of your total impact on your child, but which neighborhood do you prefer to live in? It’s a startling discovery, but Stephens-Davidowitz isn’t the only argument in considering the bigger question of how and where we live.

Author Dan Buettner traveled the world for 15 years studying the places where people lived the longest and reported being happiest for his book. blue zone, They also concluded that people underestimate how big an impact location has on their health and quality of life.

“The most important variable in that happiness recipe, the component with the most statistical variability, is where you live. If you live in an unhappy place, the best thing you can do is move to a happier place, ” He insists. And if geography has such an impact on adults, it would be surprising that it does not have as great or even greater impact on developing minds.

If you’re interested in the lesser importance of choosing a place to live, consider checking out not only Stephens-Davidowitz’s article, but also his book (this was one of Adam Grant’s summer book recommendations) or butner’s, You may also be interested in IRS data site put together by the researchers behind the study Showing which cities promote the results the most. But the basic takeaway is crystal clear.

It’s easy to worry about the little everyday decisions that crowd the lives of original entrepreneurs. So simple, in fact, that these worries can distract from an important truth—few things really matter to both you and your child’s success. Which community you choose to live in is an exception. expend more mental energy to get that right and worry less about another episode paw Patrol Or whether to serve Chicken Nuggets for the third night in a row. You’ll free up a ton of mental space for both your business and your family.
