He says there are a million trainers and gyms now, so the real differentiator is simply being excellent and building a genuine relationship with clients rather than having better equipment or marketing funnels; as he puts it, 'be fucking awesome, the end.'

It's understanding what it's like for other people to be around you — the 'you experience' — rather than just being aware of your own flaws, and it's strongly linked to emotional intelligence and better connection with others.

Harper says it's not for him — he believes airing political views publicly creates anxiety and wastes time and energy, and he refuses to be guilt-tripped into speaking out ('your silence is violence') just because others want him to.

All of his corporate speaking work for the year fell over, along with public events, workshops, camps and seminars, cutting his income to zero while he still had ongoing expenses like staff, premises rent and a company car.

It's recognising in real time what you are doing, thinking and feeling (e.g. getting anxious or frustrated) in the middle of a difficult moment, rather than just reflecting on personal development in calm, comfortable settings.

He described walking around the block, making a cup of tea, sitting down and doing about four minutes of box breathing to calm his nervous system before continuing a difficult conversation.

He is researching motivation and exercise programme adherence at Monash University's Brain Park, examining why people start exercise programs motivated but fail to sustain them, and distinguishing the academic definition of motivation (a reason) from the common emotional understanding of motivation (a feeling).

According to Craig Harper, they're based on normative data (averaging consumption across a sample group) extrapolated to the whole population, without accounting for individual variables like muscle mass, body composition, environment, and energy expenditure.
