To maximize impact, focus on problems that are large in scale, relatively neglected, realistically solvable, and aligned with your skills and strengths.
The greatest impact often comes from working on important challenges that others overlook, where meaningful progress is possible and where your unique abilities can make a lasting difference.
The central takeaway is that doing the most good requires continuous learning, critical thinking, and a commitment to following evidence wherever it leads. Effective Altruism is ultimately a methodology for improving the world, not a predetermined set of answers.
