Parenting is hard. We can find ourselves second guessing every. tiny. decision. In the end, we all want to raise happy and successful children. Here’s what parents of successful kids have in common:

1. They make their kids do chores. TED Talks “By making them do chores — taking out the garbage, doing their own laundry — they realize I have to do the work of life in order to be part of life,” Julie Lythcott-Haims, former dean of freshmen at Stanford University and author of “How to Raise an Adult” said during a Live event.

2. They teach their kids social skills. Researchers from Pennsylvania State University and Duke University tracked more than 700 children from across the US between kindergarten and age 25 and found a significant correlation between their social skills as kindergartners and their success as adults two decades later.

3. They have high expectations.  Using data from a national survey of 6,600 children born in 2001, University of California at Los Angeles professor Neal Halfon and his colleagues discovered that the expectations parents hold for their kids have a huge effect on attainment.

4. They Teach their kids math early on. A 2007 meta-analysis of 35,000 preschoolers across the US, Canada, and England found that developing math skills early can turn into a huge advantage.

5. They’re less stressed. According to recent research cited by Brigid Schulte at The Washington Post, the number of hours that moms spend with kids between ages 3 and 11 does little to predict the child’s behavior, well-being, or achievement. What’s more, the “intensive mothering” or “helicopter parenting” approach can backfire.

6. The moms work outside the home. According to research out of Harvard Business School, there are significant benefits for children growing up with mothers who work outside the home. The study found daughters of working mothers went to school longer, were more likely to have a job in a supervisory role, and earned more money — 23% more compared to their peers who were raised by stay-at-home mothers. The sons of working mothers also tended to pitch in more on household chores and childcare, the study found — they spent seven-and-a-half more hours a week on childcare and 25 more minutes on housework.

7. They teach grit. In 2013, The University of Pennsylvania psychologist Angela Duckworth won a MacArthur “genius” grant for her uncovering of a powerful, success-driving personality trait called grit. Defined as a “tendency to sustain interest in and effort toward very long-term goals,” her research has correlated grit with educational attainment, grade-point average in Ivy League undergrads, retention in West Point cadets, and rank in the US National Spelling Bee. It’s about teaching kids to imagine — and commit — to a future they want to create.
