Jonah Lehrer tells us The Truth about Grit in today's Boston Globe
In recent years, psychologists have come up with a term to describe this mental trait: grit. Although the idea itself isn’t new - “Genius is 1 percent inspiration and 99 percent perspiration,” Thomas Edison famously remarked - the researchers are quick to point out that grit isn’t simply about the willingness to work hard. Instead, it’s about setting a specific long-term goal and doing whatever it takes until the goal has been reached. It’s always much easier to give up, but people with grit can keep going.

Grit, it turns out, is an essential (and often overlooked) component of success.

The new focus on grit is part of a larger scientific attempt to study the personality traits that best predict achievement in the real world. While researchers have long focused on measurements of intelligence, such as the IQ test, as the crucial marker of future success, these scientists point out that most of the variation in individual achievement - what makes one person successful, while another might struggle - has nothing to do with being smart. Instead, it largely depends on personality traits such as grit and conscientiousness. It’s not that intelligence isn’t really important - Newton was clearly a genius - but that having a high IQ is not nearly enough.
Grit meaning "pluck" and "spirit" in addition to perseverance is an American word describing a certain American type we don't see much of anymore,
What happened?
Lewis Terman, the inventor of the Stanford-Binet IQ test, ...spent decades following a large sample of “gifted” students, searching for evidence that his measurement of intelligence was linked to real world success. ... Terman also found that other traits, such as “perseverance,” were much more pertinent. Terman concluded that one of the most fundamental tasks of modern psychology was to figure out why intelligence is not a more important part of achievement: “Why this is so, and what circumstances affect the fruition of human talent, are questions of such transcendent importance that they should be investigated by every method that promises the slightest reduction of our present ignorance.”

Unfortunately, in the decades following Terman’s declaration, little progress was made on the subject. Because intelligence was so easy to measure - the IQ test could be given to schoolchildren, and often took less than an hour - it continued to dominate research on individual achievement.
The end result, says James J. Heckman, a Nobel Prize-winning economist at the University of Chicago, is that “there was a generation of social scientists who focused almost exclusively on trying to raise IQ and academic test scores. The assumption was that intelligence is what mattered and what could be measured, and so everything else, all these non-cognitive traits like grit and self-control, shouldn’t be bothered with.”
Angela Duckworth, a psychologist at UPenn is a pioneer in the study of grit says
“I’d bet that there isn’t a single highly successful person who hasn’t depended on grit. Nobody is talented enough to not have to work hard, and that’s what grit allows you to do.”
But grit isn’t just about stubborn perseverance - it’s also about finding a goal that can sustain our interest for years at a time. Consider two children learning to play the piano, each with the same level of raw talent and each expending the same effort toward musical training. However, while one child focuses on the piano, the other child experiments with the saxophone and cello. “The kid who sticks with one instrument is demonstrating grit,” Duckworth says. “Maybe it’s more fun to try something new, but high levels of achievement require a certain single-mindedness.”
