  • Mental Filing System
    on 21/10/2019 at 12:00 am

    As you are falling asleep, do you ever think about things that you need to do the next day, but you don't want to turn on the light to write them down? The Phonetic Mnemonic System can help you remember these things in the morning. In fact, this system can be used any time that you don't have a pen and paper handy. To do this, simply associate the thing that you need to do (go to the bank) with a phonetic keyword for 1 (tie). Visualize the next thing that you need to do (pick up dinner) with a keyword for 2 (knee). When you wake up in the morning, you simply need to go through your keywords to remember the things that you need to do. A variation on this method is to group your keywords by category. For example keywords 1-10 could be used for things related to work, keywords 11-20 could be for things related to home, and so on. This will help mentally organize your to-do list. To reduce interference between days, you could use different keywords for each day of the week. Monday uses keywords 1-10, Tuesday 11-20, etc. Pick the method that works best for you.

    As it often happens in life evil warlock imprisoned a wise man. Surprisingly he gave him a chance to save himself if he fulfils one task. There is a round tray on the table which can be turned around freely. There are four coins on the tray placed as corners of a square. Wiseman has his eyes covered so he doesn’t see anything. His task is to turn the coins so that they are all heads up. He is not in easy situation. He may turn some coins and than the warlock will turn the tray around. He turns some coins again warlock turns the tray again. It goes on until all coins are turned correctly. At that moment evil warlock ends the game. Wiseman can’t recognize one side from the other by touching it. He has to leave the coins where they were in the corners of a square. And mainly – because of the evil magic – he has the worst luck so if he relies just on chance he will never fulfill the task.

When they wake up in the morning they look at each other and all start laughing. If one of them realizes he is black too he stops laughing. Because they are all smart and they know it about each other one of them will realize it soon. How did he find out? Just realize that if two friends are dirty it means that I am too.
