Values work is the first stop in almost every coaching programme, and Greenberg has spent years studying why it so often fails to produce insight. His team's research mapped all human intrinsic values — things valued for their own sake, not as a means to something else — and found 22 distinct categories, from longevity and reducing suffering to connection, adventure, nature, and spirituality. The human brain encodes preferences directly, but determining whether something is truly intrinsic requires an extra cognitive step most people never take. Greenberg describes a friend who was inexplicably depressed despite having a 'great' boyfriend: when he asked her to list her own values and then her boyfriend's qualities, there was zero overlap. When he asked her to list her parents' values, it was a perfect match. She had been living out her parents' ideal life, not her own. The story illustrates how years or even decades can pass with people confusing what their culture or family values with what they themselves value intrinsically — and how a simple mapping exercise can make the mismatch instantly visible.

Spencer Greenberg and Jeremy Stevenson analyzed almost 500 self-improvement techniques and found they all reduce to just 12 underlying psychological drivers.
Cold exposure has good short-term alertness benefits but the evidence base for long-term health benefits is much weaker than popularly believed.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
A study found that simply scheduling enjoyable activities was as effective as standard cognitive behavioral therapy for depression, leading to its own therapy called behavioral activation.
The 'worry time' technique — deferring all worries to a designated time of day — helps people realize they have more control over worry than they thought and reveals it is less useful than it feels.
A study found that participants told to try to stay awake while in bed fell asleep faster than participants told to try to sleep — illustrating the paradox of direct effort.
Spencer Greenberg reduced his severe social anxiety dramatically in roughly 6 months through a structured exposure therapy hierarchy, culminating in asking strangers for hugs.
Making the first hour of your day high-cortisol and the last hour low-cortisol is described as the single most impactful daily habit for mood, focus, alertness, stress resilience, and sleep quality.
