Micromastery is a triumph. A brilliant idea utterly convincing and superbly carried through - Philip Pullman We read that we must be passionate about only one thing that 10000 hours of hard practice is needed to achieve mastery. But in fact most successful people including Nobel prize winners nurture multiple areas of knowledge and activity that feed their central subject. Whether its making a perfect souffle dancing a tango or lighting a fire when we take the time to cultivate small and quantifiable areas of expertise we change everything. We become faster and more fearless learners spot more creative opportunities improve our brain health and boost our happiness. We see knowledge itself completely differently. The skills acquired in painting a door flawlessly or growing delicious chillies will unexpectedly transform your life. So start small. Start specific. But start - and youll be on the path to mastery.
