Annie Duke helped an ER doctor realise that her explicit probability estimate of 0% happiness if she stayed in her current job versus 50% if she took a new one made the right decision obvious — she quit the next day.

Drawing on Kahneman and Tversky's prospect theory — losses feel about twice as intense as equivalent gains — Annie explains that when we consider a risky new option, we obsessively model its bad outcomes while never applying the same scrutiny to the current situation we're already living. The doctor who hated her ER job for years and had a new opportunity finally responded to one explicit question: 'What are the chances you're happy a year from now if you stay?' Zero. 'What if you take the new job?' Fifty-fifty. She quit the next day. Annie then introduces the pre-mortem: before committing to a big decision, deliberately imagine it has failed and ask what went wrong and what the warning signs were. This is the decision-making equivalent of Stoic negative visualisation, and it metabolises the fear of failure in advance — making you less loss-averse about the choice and more prepared to course-correct if things do go wrong. She also corrects the one-way-door/two-way-door metaphor: everything is quittable, just at different costs.
In poker and in life, increasing volume of decisions (more hands played, more bets placed) shifts outcomes from luck-dominated to skill-dominated, gradually washing out variance.
Before making a major decision, deliberately imagine that it has failed. Ask: what went wrong, what were the warning signs, how would I have known earlier? This is what Annie Duke calls a pre-mortem, and it mirrors the Stoic practice of negative visualisation. It reduces loss aversion, metabolises the fear of failure in advance, and gives you a detection framework so you can course-correct faster if things do go wrong.
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.
In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
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.
