Learning 1 · Introduction
Tiger vs Roger
The idea
Tiger Woods specialised in golf from toddlerhood. Roger Federer played many sports before focusing on tennis later. Epstein argues Federer's path is more common among elite performers.
Takeaway
Early specialisation isn't the only route to excellence.

Kind and Wicked Environments
The idea
In 'kind' learning environments like chess or golf, patterns repeat and feedback is quick, so early specialisation works. In 'wicked' ones, rules are unclear and feedback is slow.
Takeaway
Most of life is wicked. Range helps there.

Learning Fast vs Learning Well
The idea
Desirable difficulties, like spacing and mixing practice, slow learning now but improve long-term retention.
Try this
Mix different types of problems instead of practising one type at a time.

Ask how an unrelated industry solves a problem like yours.

Outsiders Solve Problems
The idea
Outsiders sometimes solve problems experts can't, because they bring different approaches.
Example
Open innovation platforms where solutions come from people in other fields.

Learning to Drop Familiar Tools
The idea
In crises, people who cling to familiar tools and routines can fail. Knowing when to drop them is vital.
Example
Firefighters who died carrying heavy tools they could have dropped to outrun a fire.
