Mark Zuckerberg: “You can’t 80/20 everything” When Facebook started, Mark Zuckerberg and Dustin Moskovitz had a tough decision to make. For each college they launched Facebook at, they had to clean up data from course catalogs to make sure everything was accurate. Dustin suggested skipping this step to move faster, but Mark insisted on doing the extra work. Mark believed that having clean, reliable data made Facebook feel trustworthy and special for college students. This extra effort helped set the tone for the platform’s quality and culture in its early days. Later, Mark reflected on this decision and shared an important lesson for entrepreneurs. He said while the 80/20 rule is useful (getting 80% of results with 20% of the effort), you can’t rely on it for everything. To stand out, you have to go the extra mile in some areas and be the absolute best at them. His advice: Focus on the things that truly matter for your product or service. Put in the extra effort where it counts, even if it’s harder or takes longer. This dedication to quality can set you apart and help you build something truly exceptional.
