“Random Reminder” is a new focus method designed to help you enter deep focus quickly. More than 400 people worldwide use it every second. With this method, you can stay focused for up to 90 minutes, improve your attention and memory, and enter a flow state more easily. == A New Focus Method == - Set a sound to play at random intervals (e.g., every 3–5 minutes). - Each time you hear the reminder sound, immediately close your eyes and rest for 10 seconds. - Then return to your work or study and continue focusing. Repeat this process until the 90-minute session ends. - After 90 minutes, take a 20-minute break. == Based on Four Core Principles == ■ Neural Replay During micro-breaks, your brain "replays" recently learned information at high speeds, improving memory retention and learning performance. ■ Variable Ratio Reinforcement Randomized feedback keeps the brain’s dopamine system engaged. Not knowing exactly when the next sound will occur maintains a healthy level of alertness and motivation. ■ Zeigarnik Effect Briefly interrupting a task creates a psychological "open loop." This makes your brain more eager to complete the task, helping you dive back in more effectively. ■ Ultradian Rhythms (90/20 Rule) The human brain naturally operates in 90-minute high-frequency cycles. Following this rhythm prevents burnout and maximizes mental endurance. ====== Personal growth website: https://zeenzeen.com Creator: 择恩 ====== “Random Reminder” can be downloaded and used for free.
