I do not think of myself as a patient person, which it turns out is a shame because patience is a virtue that makes people happier.

Patience, the ability to keep calm in the face of disappointment, distress or suffering, is a virtue that is worth cultivating. It is associated with a variety of positive health outcomes, such as reducing depression and other negative emotions. Researchers have also concluded that patient people exhibit more prosocial behaviors like empathy, and were more likely to display generosity and compassion.

A 2012 study in the Journal of Positive Psychology identified three distinct expressions of patience: 1. Interpersonal, which is maintaining calm when dealing with someone who is upset, angry or being a pest. 2. Life hardships, or finding the silver lining after a serious setback. And 3. Daily hassles, which is suppressing annoyance at delays or anything irritating that would inspire a snarky tweet.

I’m ok with (1) and (2) but rubbish at (3). The good news is that is that same study found that patience as a personality trait is modifiable so whilst I can congratulate myself for the first two types of patience, it is entirely possible, old as I am, to work on the third. Even if you’re not a particularly patient person today, there’s apparently still hope you can be a more patient person tomorrow.

Impatience is the “fight” component of the fight-or-flight response, according to M.J. Ryan, executive coach and author of The Power of Patience: How This Old-Fashioned Virtue Can Improve Your Life. “That’s why you’re beeping your horn at people in the car or getting annoyed in the queue or whatever it is you’re doing that’s your impatient behavior,” she said.

Amygdalae are the culprit. This almond-shaped set of nervous tissue in our brains is responsible for sussing out threats and regulating emotions. While this component of the limbic system is perfectly calibrated for protecting our ancestors from ferocious predators, it’s not as adept at determining credible threats in modern life. Sometimes it feels as if we interpret threats to our status e.g.. who gets served first or fastest in a restaurant, as more life threatening events.

Because we are poorly set up physically to differentiate between types of threat, we can overreact. The amygdala, Ms. Ryan said, is too unsophisticated to know the difference between a true danger (say, a growling tiger) and something substantially less life-threatening (dealing with an obnoxious person).

Figure out which situations set you off — careless drivers, technological glitches, slow-moving cashiers, slow service in a restaurant etc. — and you’re already on your way to taking control.

Next, think about what thought or suspicion sets off the alarm bells in your brain. “There’s something that you’re either saying to yourself, an image you have, a feeling in your body that is triggering that response, that you’re under threat,” Ms. Ryan said.

Once you figure out what you’re telling yourself about the situation — “I can’t be bothered to wait in this queue,” for example — then you can address your internal concern, interrupt the stress response cycle and stay out of fight-or-flight mode. For example: If standing in a long queue drives you crazy, an appropriate mantra might be, “I’m in no rush at the moment.” For those who blow a fuse circling for parking spaces, a mantra that might work could be, “I’ll find a spot eventually.”

The idea is to take a step back from the situation and try to look at it as objectively as you can. Is waiting in this long queue inconvenient? Sure, but be realistic and practical: It will soon pass, and, in all likelihood, you’ll forget it ever happened.

Next, spend a beat thinking about the worst case scenario. What’s the actual consequence of standing in the queue at the bank another 10 minutes or restarting a finicky device? Do any of these outcomes constitute a life-or-death threat? “Almost always, always, always, no is the answer,” Ms. Ryan said.

Sarah A. Schnitker, an associate professor of psychology and neuroscience at Baylor University and a leading researcher on the topic of patience, suggests using a powerful technique called cognitive reappraisal, which means thinking about a situation differently.

Take, for example, someone aggravated with a nitpicky co-worker. Instead of dwelling on your irritation, you could think about the times you’ve been the one who has frustrated others.

“Give grace to each other,” Dr. Schnitker said. Or perhaps more difficult to achieve, try to think, “you know what, this is actually helping me to grow as a person.” This could be as simple as acknowledging that the slow elderly lady ahead of you in the queue is just struggling with age, the need to connect meaningfully with another person within a lonely life, the physical disability that comes with arthritic fingers or failing eyesight counting out coins – and we will hopefully all grow old and expect to be treated kindly.

Another strategy she recommends is to focus on why and how patience is integral to your values.

“For instance,” Dr. Schnitker said, “if I were talking to a parent who is struggling with their kid, I’d say, ‘Well, first, let’s think about the really big picture: Why is being a parent an important role to you? What does that mean in your life?’”

Thinking about how patience ties into your larger sense of integrity and poise “will make it a whole lot easier to stick with practicing patience on a daily basis and building up those skills,” she added.

Perhaps the most common mistake people make is thinking sheer will can turn them into a more patient person, Dr. Schnitker said. If you do that, she cautions, you’re setting yourself up to fail. Just as marathon runners don’t run a marathon on their first day of hitting the trails, people who are serious about cultivating patience shouldn’t expect immediate results.

“You want to train, not try, for patience,” she said. “It’s important to do it habitually.”

She suggests practicing patience during less intense, even silly situations when the stakes aren’t so high. Reappraise a situation next time you notice you’re feeling short-tempered, practice mindfulness meditation or say your own custom mantra.“It’s like any other skill,” Dr. Schnitker said. “If you do it on a daily basis and then also connect it to that bigger picture story of why it’s important, it can grow and develop just like a muscle.”

Now that you know your triggers and are working on staying out of fight-or-flight mode, incorporate some stress reduction measures. If your impatience trigger is killing time in waiting rooms, designate a game on your phone that you play only when you’re at the doctor’s office. If you detest being in traffic, leave for appointments earlier. If you abhor crowded grocery stores, run your errands at off-hours.

Finally, Nedra Glover Tawwab, a licensed clinical social worker based in Charlotte, N.C., recommends being more sensible about setting achievable aims.

“Sometimes we overbook ourselves or we don’t allot enough time to do things,” she said. “Be reasonable in setting your own goals for yourself because there’s only so many things that you can do in a time frame or any day. ”If your to-do list has 10 items on it but you can only reasonably accomplish five, then you’re sabotaging yourself. Any inconvenience has the potential to throw you off-track when your day is planned down to the minute.

“I can’t fast forward time and I can’t make people move faster,” she said. “I can’t manipulate those things; the only thing I can manipulate is me.”
