Why Willpower Won't Fix Your Interview Nerves

For a decade, the advice from Angela Duckworth's bestseller Grit was to dig deeper: passion and perseverance would carry you through. Her new book, Situated, released September 1 and already the subject of an NPR interview and a Philadelphia Magazine profile this week, walks that back in an important way. Grit isn't wrong, she says, it's just not enough on its own. What actually determines whether you perform well is often the situation you've put yourself in, not how much willpower you can muster in the moment.

The shift from "try harder" to "change the setup"

Duckworth's line, quoted in her NPR interview, is blunt: "though you're often told to make the best of your situation, it is far, far better to make your situation better first." Her argument is that people who consistently perform well under pressure, in leadership, athletics, or business, aren't relying on raw discipline. They're actively designing four things around themselves: the physical objects within reach, the peers and mentors they surround themselves with, the norms of the environment they're in, and the spaces they practice or work in. She points out that "every CEO I interviewed has some kind of executive coach or advisor," and that athletes are constantly asking "is this the right coaching team?" rather than just trying to grit their way to improvement alone.

Why this matters for interview and speech prep specifically

This maps almost exactly onto a mistake a lot of people make when getting ready for an interview, a sales pitch, or a big presentation. The default approach is to sit alone with notes, rehearse mentally, and hope that when the moment comes, nerves won't get the better of you. That's a willpower strategy, and Duckworth's research suggests it's the weaker one. The stronger strategy is to change the conditions of your practice so that good delivery becomes the default, not something you have to force under pressure.

Concretely, that means practicing out loud in a room that resembles the real setting, not silently reviewing bullet points. It means finding a person, a coach, a mentor, even a peer, who will listen to a run-through and give you real feedback, rather than practicing in isolation and hoping you sound as good as you think you do in your head. And it means noticing that if you consistently freeze or ramble in interviews, the fix probably isn't "try to relax more." It's closer to what Duckworth calls a misaligned situation: your prep environment doesn't match the demands of the real one.

How to apply this before your next interview or pitch

  1. Practice out loud, in a comparable setting. If your interview is over video, rehearse over video, sitting in the same kind of chair, with your camera on. Matching the environment is doing part of the work that willpower would otherwise have to do.
  2. Recruit a coach or peer reviewer, don't go solo. Ask someone to listen to a full run-through and flag specific moments, not just "how did that sound overall." An AI coaching tool like SpeechPlus can fill this role when a person isn't available, giving you feedback on pacing, filler words, and clarity you can't hear in your own head.
  3. Remove friction, not just distractions. Duckworth's "objects within reach" point applies directly here: have your notes, your questions for them, and your water within arm's reach before you start, so you're not fumbling mid-answer.
  4. Build a norm of practicing, not just cramming once. One rehearsal the night before is a willpower move. Three or four shorter sessions across a week, each with feedback, is a situation-design move, and it's the one more likely to hold up under real pressure.
  5. Diagnose repeat problems as a setup issue first. If the same weak spot shows up interview after interview, don't default to "I need to try harder." Ask what about your prep setup isn't matching the real demands, and change that first.

The bottom line

Duckworth's own pivot from Grit to Situated is itself a useful lesson: even the researcher who made willpower famous is now arguing it's not the lever to pull first. Before your next interview or pitch, spend less energy trying to psych yourself up and more energy building a practice setup, the room, the feedback, the repetition, that makes good delivery the path of least resistance.
