Part 1: What makes for a dream job? Answer: Research shows that to have a fulfilling career, you should do something you’re good at that makes the world a better place.

Part 2: How much difference can one person make? Answer: Many common ways to do good, such as becoming a doctor, have less impact than you might first think. Other, more unconventional options, have allowed certain people to achieve an extraordinary impact (including one particular Lieutenant Colonel in the Soviet military).

Part 3: Can you change the world without changing job? Answer: With the right approach, you can make a major difference to the lives of others without changing job, or making a major sacrifice.

Part 4: Where should you focus to have the most impact? Answer: To maximise your impact, work on areas (1) that are large in scale, (2) that others neglect, and (3) where it’s possible to make progress. Many people fail to compare the scale of different problems, work on the same problems as everyone else, and support programmes with no evidence of impact.

Part 5: What’s the biggest and most urgent problem in the world? Answer: Most people in rich countries who aim to do good work on health, poverty and education in their home country. But health in poor countries is a bigger, more solvable problem, and only receives 4% of charitable donations. Others work on climate change, but pandemics pose a similar threat, and are over ten times more neglected.

Part 6: Which jobs help people the most? Answer: When we think of jobs that help people, medicine, teaching and charity work are what first come to mind. But these are not always the highest-impact options. To help the most people: (1) focus on the most pressing problems; (2) choose the best method for working on the problem, considering research, advocacy and donating to charity, as well as direct work; and (3) do something with excellent personal fit and job satisfaction.
