She works with leaders all over the world to help them achieve mental resilience and peak brain performance, improving their ability to manage stress, regulate emotions and retain information. Why should I not have caffeine after 12 o’clock every day? The quarter life of caffeine is 12 hours, so 12 hours after you have your last caffeine, a quarter of that is still buzzing around your brain. What are the benefits of cold showers? Ideally, the research that is most ideal is an ice bath followed by a sauna. But while that’s not mostly practical for all of us, there’s some research from Finland that’s shows there’s some benefits of a 15, 30 or 60 second cold shower because it has a beneficial effects of our immunity from colds and even if you do get sick it reduces the number of days you get sick. What you want to do is shock your body and show it that you can control your recovery afterwards, so it’s important to have the cold shower first then warm yourself up afterwards. It’s almost like a form of inoculation. Why should I not have too much alcohol particularly within 2 minutes of bedtime? Timing is really important here, and its binary, which is that even small amounts of alcohol have a disproportionate effect on your sleep. Any consumption, eating or drinking means that your body can’t go into recovery during sleep until you’ve digested or dealt with any toxins (like alcohol) even if you don’t drink alcohol or you eat late, it will still disturb you. Why should I not look at my phone during the night? Any devices that admit blue light, (which mimics natural daylight) there’s a gland called the pineal gland which releases melatonin one hour before we fall asleep and the blue light disrupts that process. There is an app called flux that makes the light on your devices more orange, which is helpful, but it’s also because your brain is buzzing with the latest thing that you’ve read and stops the winding down process. Even checking it for 2 seconds, the blue lights effect on you can be disastrous for this process. There is even evidence that it can increase your cancer risk – which is due to the body not adopting the natural day and night cycles. What are the positive impacts of practicing some form of gratitude? It’s so easy to go through life and not pause and think about what you’ve accomplished and move on to the next thing, and the reason for that is to ensure our survival our brains are geared more to avoid a loss than to seek a reward, we focus on the negatives about twice as much as we focus on the positives. I do a list of 10 things and write them down. Gratitude brings to the front of the mind the more positive, abundant style of thinking and in the research that I’ve done, I’ve found that overtime that list develops and moves more from the external things like friends and family that you are grateful for to more intrinsic capabilities like my resilience my creativity, my adaptability my ability to solve problems. Once you really acknowledge that to yourself you start to feel like ok, if something bad happens to me, I’m more aware of the capabilities I have to deal with that. So, when there’s a crisis, you know you can get through it.

What if high performance isn’t just winning, but winning without sacrificing your health, relationships, or sense of purpose? Shaun sits down with James Laughlin to unpack the habits that drive sustainable success on the field and off it. James shares practical frameworks for decision-making, prioritisation, and building routines that protect energy and prevent burnout. Guest Bio James Laughlin is a high-performance coach, keynote speaker, and author of Habits of High Performers. A former multi-time world champion, he now works with leaders, athletes, and high-performing teams to build sustainable habits that drive results without burnout. Episode Summary James reflects on the reality that external success can hide internal struggle. Despite becoming a world champion, he was running on low sleep, leaning on alcohol, overworking, and watching his marriage deteriorate. That experience sparked a deeper question: Can you perform at a high level professionally while also thriving personally? Together, Shaun and James challenge the idea that high performance means doing more. Instead, they explore habits that help people succeed with clarity and consistency - learning to say “no,” creating a values and priorities filter for decisions, building momentum through routines, and shaping environments that support growth. They also discuss the role of purpose, how elite performers manage self-doubt, and why “counterbalance” matters more than chasing work-life balance. Key Discussion Points · A healthier definition of high performance: success with wellbeing and strong relationships · Why high performers say “no” more often than most people · The Values & Priorities filter for clearer decision-making · Choosing long-term priorities over short-term ego wins · Consistency beating motivation, and why discipline is temporary · Intrinsic vs extrinsic motivation and how it shapes behaviour · Capturing wins to manage self-doubt and imposter syndrome · How gratitude and reflection shift mindset · Environment design: people, culture, and physical space · Relationship systems: boundaries, rituals, date nights, and planning time in advance · “Habits over hustle” and using counterbalance to avoid burnout · Intention as a defining trait of elite performers · Purpose as a protective factor against burnout and unhealthy coping Timestamps 0:00 – Shaun's intro and sponsorship mention 0:35 – James returns to the show and the story behind the book 2:01 – World champion success vs the hidden cost off the field 4:09 – Redefining high performance beyond "winning" 4:41 – Saying no as a key high-performance habit 5:33 – The Values & Priorities filter 7:06 – Choosing Finn's school production over a major London event 9:01 – Consistency, discipline, and habit formation 9:27 – Intrinsic vs extrinsic motivation 13:07 – Self-doubt, imposter syndrome, and the Personal Victory Journal 15:28 – Gratitude and scanning for what's going right 17:45 – Culture and environment: "lifters vs leaners" 19:42 – Relationships and boundaries that protect what matters 23:56 – Counterbalance vs work-life balance 27:24 – Intention and execution as the separator 30:27 – Purpose and meaning as burnout prevention 33:40 – Three habits for 2026: routine, standards, reading 36:32 – How long habits take to stick (66 days on average) 37:34 – Where to find James and what's coming next
