People take care of things. They survive if their clothes get dirty. Or scratch a car. Do not carry the phone without a case. At the same time, they don’t even think about garbage that every day gets into the head, pollutes thoughts, dulls the intellect.

Few people clean the cloud of information in their heads from useless nonsense or systematize it inside for faster access and convenient use. But the main asset that no one can ever take away from us, stain, break it is experience.

With the right knowledge, you can buy clean clothes, an unbroken car and a new phone. Eat well. Get warm. See the world.
