You have 80,000 hours in your career. That’s a long time. Spend one or two of those hours on this guide, to help you work out how to use the rest. We believe you might be able to find a career that is both more satisfying and has a greater positive impact.

Answer: Research shows that to have a fulfilling career, you should do something you’re good at that makes the world a better place. Don’t aim for a highly paid, easy job, or expect to discover your “passion” in a flash of insight. Find out the six key ingredients of fulfilling work.

Answer: Don’t just send out your CV in response to job listings. Get leads through your connections, and prove that you can do the work by actually doing some. When you get an offer, negotiate.

Here we offer a summary of all the best advice on how to get the job you want.

Answer: Join a community of people working in the same area as you. You’ll get hundreds of connections at once. And two people working together effectively can achieve more than they could individually. Every community’s unique, so try out several and see which are best for you and your career. If you liked this guide, then you’ll probably share aims with lots of people in the effective altruism community, which we helped start back in 2011.

Here we explain how being part of a community can help.

We sum up the whole guide in a few minutes.

Lots of people say they want to “make a difference,” “do good,” “have a social impact,” or “make the world a better place” — but they rarely say what they mean by those terms.

By getting clearer about your definition, you can better target your efforts. So how should you define social impact?

The trouble with self-help advice is that it’s often based on barely any evidence.

Much other advice is just one person’s opinion, or useless clichés. But at 80,000 Hours, we’ve found that there are a number of evidence-backed steps that anyone can take to become more productive and successful in their career, and life in general. And as we saw in an earlier article, people can keep improving their skills for decades.

Over the last couple of decades, a large and growing body of research has emerged which shows that our decisions are far from rational. We did a survey of this research to find out what it means for your career decisions.

As part of our research, we’ve evaluated different careers: how likely people are to succeed in them, how much good they could do in them, and how to enter them.

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).

We aim to list issues where each additional person can have the most positive impact. So we focus on problems that others neglect, which are solvable, and which are unusually big in scale, often because they could affect many future generations — such as existential risks.

Answer: With the right approach, you can make a major difference to the lives of others without changing jobs, or making a major sacrifice. You can do this by giving 10% of your income to the world’s poorest people, promoting important causes, or helping others to have a greater impact.

Listen to learn about three ways to make a difference in any job.

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.

In this article we explain how to compare global problems.

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. And we argue there are even bigger and more neglected issues, such as those involving existential risks and smarter-than-human AI.

Here we explain what we’ve learnt about the world’s most urgent problems.

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, think broadly about the paths where you can make the biggest contribution, including research, communications and community-building, taking high-earning jobs to donate to charity, government and policy, and organisation-building.

Here we lay out five types of high-impact career.

Answer: Especially early in your career, take options that will give you career capital — skills, connections, credentials, character, and runway that put you in a better position to make a difference. Examples include working at high-performing growing organisations, graduate studies in certain subjects such as economics, or learning concrete skills like information security or China expertise. Be careful with humanities PhDs, charity jobs, and vocational qualifications.

Here we lay out many strategies for putting yourself in a better position.

Answer: Don’t expect to figure out what you’re best at right away, especially through introspection, going with your gut, or career tests. Instead, think like a scientist: make best guesses, clarify your key uncertainties, and then investigate those uncertainties by doing research and cheap tests. Early in your career, consider trying out several paths, and when in doubt, aim high.

In this episode we suggest ways to find the best career for you.

Answer: Rather than try to pinpoint the single best option, accept that your plan is likely to change. But don’t try to “keep your options open”. Instead, think about your career in three stages: exploring, building career capital, and deploying that career capital to have an impact. Then, sketch out a plan A, but also a plan B and plan Z in case it doesn’t work out. Update your plan every couple of years.

Here we explain how to make a flexible A/B/Z career plan.
