How should you effectively prioritize tasks on a to-do list?

According to Charles Duhigg, effective task prioritization requires moving beyond using lists merely as memory aids. He recommends creating a daily to-do list with no more than three items, focusing on what will have the most impact. The first item should be the most important task that will create significant impact, the second being something that absolutely must be completed that day, and the third as a bonus if time permits. This approach follows the 80/20 principle, emphasizing quality over quantity. By intentionally selecting just a few high-impact tasks each morning rather than working from an overwhelming list of 20+ items, you'll make meaningful progress on what truly matters instead of gravitating toward easier, less important tasks.
