This is your most important decision

And we’re going to show that — if you have the privilege to have options — you can probably increase the impact of your career not just by a little, but by a huge amount.

From adulthood, you’ll spend almost half your waking hours on your career — more than the time you’ll spend eating, on hobbies, and watching Netflix put together. So unless you happen to be the heir to a large estate, that time is the biggest resource you have to help others.

This makes your choice of career the most important ethical decision of your life.

You have about 80,000 hours in your career: 40 hours per week, 50 weeks per year, for 40 years.
