Do you know what? Sometimes, even if you know of something, you have to not rely on your notes nor even look at it or have it at sight because your brain becomes confused whether to exert effort or not. In such case, your mind becomes unstable and you will look like as if you do not know anything about something which you actually know.We are so afraid to the invisible that we devise something to aid or feed us. We are not handicaps. Remember.Know that when you know it, the brain will do its job for you to find the information you are seeking. The doubt that you have cast upon yourself gives the feeling of insecurity to your brain.Eat the consequence of your own capacity rather than fool yourself with a fake capacity due to lack of self-trust.
