• A scientific approach to getting good at things and becoming an expert

• From the creator of the 10,000 hour rule: But not strictly true

• Hours spent is the key determining factor but in the right way

• Hours spent doing the wrong type of practise get worse/don't improve

• Doctors who believe their skills are good enough already

• Wrong practise? No feedback, no comparison, no guidance on right or wrong - aimlessly putting in the reps = bad.
