Walking is not as easy as you'd think. The physical and mental effort involved is far beyond what any other activity requires, and will take multiple years of training to fully master.

How to walk
1. To walk, you will need to use the WASD keys. Make sure you know where these keys are on your keyboard so that you can use them while in a game.
2. To press these buttons, you will need to use your fingers. Therefore you should spend 30 minutes a day stretching your fingers so that you don't strain them during gameplay.
3. After warming up your fingers, you should next prepare mentally. Imagine yourself successfully performing the task of walking.
4. Break down and cry because the task is too mentally taxing.
