No, multitasking is often a misconception when it comes to productivity. While it might seem like you're achieving more by juggling multiple tasks, you're often draining your cognitive resources, leading to more mistakes and longer task completion times.
Research indicates that our brains aren't designed for multiple attention-diverting tasks. Instead of multitasking, focusing on one task at a time—single-tasking—can improve accuracy, reduce stress, and enhance overall productivity. In essence, doing one thing well is more effective than doing many things subpar.
