2 Stubborn Habits That Predict Long-Term Success (Backed by Psychology) (2026)

In the realm of self-improvement, where every clickbait headline promises the next big productivity hack, it's easy to get lost in the noise. But amidst the endless scroll of tips and tricks, there's a refreshing reminder of the timeless habits that truly predict long-term success. As a psychologist, I find myself drawn to the idea that the most effective strategies for achieving success are often the simplest and most stubborn. Two habits, in particular, stand out as the cornerstones of sustained achievement: tolerating boredom without abandoning the task and consistently choosing the harder option when the easier one is available.

The Power of Boredom Tolerance

What separates high achievers from the rest is not always passion or talent, but rather the ability to endure tedium. This is where the concept of grit comes into play. Grit, as defined by a landmark study, is the perseverance and passion for long-term goals, and it consistently predicts achievement across various populations. The key insight here is that gritty individuals are not immune to boredom; they simply choose to keep going, even when the task at hand becomes less exciting. This is where distress tolerance plays a crucial role. Distress tolerance is the capacity to endure uncomfortable psychological states, such as boredom, without giving in to the urge to escape. A recent study found that students who develop real expertise often face long stretches of work that feel neither rewarding nor stimulating. Those who learn to tolerate these stretches outperform their peers, even when their raw ability is comparable. This challenges the notion that the most productive people are the most motivated; instead, they are simply better at being bored.

In today's media-driven world, where distractions are ever-present, the ability to sustain attention on tedious work is becoming a rare and valuable skill. The writers who finish their manuscripts, the researchers who delve deep into a single question for years, and the engineers who debug the unglamorous code are not more passionate than their peers. They have simply built a higher threshold for staying when staying is hard. This habit of tolerating boredom and refusing to treat it as a signal to quit is a competitive advantage that often goes unnoticed.

The Art of Choosing the Harder Path

The second habit is closely related but operates on a different level. It's about the deliberate decision to delay immediate gratification for something more meaningful later. This concept is rooted in Walter Mischel's famous marshmallow experiments, where children were offered a choice between eating one treat immediately or waiting for two. The follow-up work suggested that those who could wait tended to have better outcomes years later. More recently, a large-scale study found that effortful persistence, a key dimension of grit, was significantly associated with career success, including income, job satisfaction, and engagement behaviors. This research reveals that the capacity to delay gratification is not a fixed trait but rather a practiced orientation, a value hierarchy that is repeatedly acted upon until it becomes the default.

The entrepreneur who passes on social events to build a company is not suffering through deprivation; they have simply decided what matters, and each consistent choice reinforces that decision until the difficult option stops feeling difficult. This is the essence of stubbornness in habits. Repetition changes the calculus, and what begins as an effortful act of self-denial gradually becomes an expression of identity. The person who consistently chooses the harder option is not white-knuckling through every decision; they have reoriented what feels natural over time.

The Common Foundation

Both habits share a common foundation: tolerating short-term discomfort in service of long-term goals. The original grit research found that this quality predicted success above and beyond IQ, highlighting the compounding effect of sustained effort. The returns on showing up, tolerating tedium, and choosing the harder path repeatedly are not fully captured by conventional measures of ability. These habits are easy to drop, and most people do, often switching tabs when boredom strikes or opting for the easier path. However, the research suggests that long-term success tends to accumulate in those moments where most people have already moved on.

The Takeaway

In the pursuit of success, it's easy to get caught up in the latest trends and tips. But the truth is, the most effective strategies are often the simplest and most stubborn. Tolerating boredom without abandoning the task and consistently choosing the harder option are habits that require a willingness to stay uncomfortable for longer than feels reasonable. These habits are not about white-knuckling through every decision but rather reorienting what feels natural over time. By embracing these stubborn habits, we can unlock the potential for sustained achievement and discover the competitive advantage that lies in plain sight.
