Anil NattuEvidence Quote
“His core insight is arguably the most important principle of modern productivity. He said, 'The mind is for having ideas, not for holding them.' I want to pause and just let that breathe because it is so profound... It is deeply rooted in cognitive psychology, specifically the Zeigarnik effect, which states that people remember uncompleted or interrupted tasks better than completed tasks.”
