A mindset is the set of ideas, beliefs, or attitudes with which you approach situations or through which you view them. Mindsets have something in common with habits since they tend to be habitual, which means somewhat unconscious.

You can have mindsets about yourself, another person, a group of people, a place, a time of year, a type of music, a political organization—actually just about anything. A mindset is not just an opinion. It is more complex than that.

And it can have surprisingly far-reaching effects.

Dueling Mindsets

Some mindsets have more profound effects on our lives than others. In her 2007 book Mindset, Carl Dweck describes two general mindsets—the fixed mindset and the growth mindset—that can lead to quite different experiences and outcomes.

In a fixed mindset, people believe their basic qualities, like their intelligence or talent, are simply fixed traits. They spend their time documenting their intelligence or talent instead of developing them. They also believe that talent alone creates success—without effort. They’re wrong.

In a growth mindset, people believe that their most basic abilities can be developed through dedication and hard work—brains and talent are just the starting point. This view creates a love of learning and a resilience that is essential for great accomplishment. Virtually all great people have had these qualities.

Dweck’s work on mindsets has been applied to the field of education, where children’s mindsets are often formed. Children praised for their talents and abilities (fixed mindset) tend to avoid taking on challenges they think are beyond their abilities. Children praised for their effort and persistence (growth mindset) tend to take on additional challenges in order to learn from them.

Be Good vs. Get Better

Following in Dweck’s footsteps, Heidi Grant Halvorson describes these two mindsets as Be Good and Get Better. People who have a Be Good mindset are focused on proving themselves, demonstrating their skills, and comparing themselves to others. If they think they aren’t already good at something, they tend to either not want to try to do it or to give up if they don’t experience quick success.

People who have a Get Better mindset are focused on improving, rather than proving, themselves; developing, rather than demonstrating, their skills; and comparing their current performance to their own past performance rather than to others’ performance. They aren’t afraid to try something new because even if they’re no good at it now, they can always get better.

The Be Good mindset may be good when it comes to performance, but it doesn’t have much else to recommend it. People with a Get Better mindset generally handle challenges better, get less upset when things go wrong, don’t give up as easily, are more comfortable with the new and the unknown, and get more interest and enjoyment out of what they do. People with a Get Better mindset use whatever happens to them—the good, the bad, and the ugly—as well as their own missteps and miscalculations, to help them get better.

This type of mindset isn’t a black-or-white kind of thing. You can have a Be Good mindset about some things and a Get Better mindset about others. It’s worth cultivating a Get Better mindset in as many areas as possible. But, as Halvorson says, it’s important to have a Get Better mindset about changing to a Get Better mindset.
