Simply being able to draw beautifully is no longer enough. It's important to create value by understanding user psychology and applying this knowledge to improve products. Because a modern product becomes part of people's lives, so it must be so convenient that it's hard to refuse.

That's why I decided to create this collection, in which I gathered 100 fundamental laws and principles that help create interfaces that truly work.
It will be useful for everyone: designers, product managers, marketers, SMM specialists and other professionals, and will help expand worldview and teach strategic thinking and creating friendly and successful products.

I explained each law and principle using real examples to make it easier for you to understand how to apply them specifically in interface design.
Because knowing a law is one thing, but understanding how to implement it in practice, especially in interfaces, is completely different.
These principles will become the foundation that transforms your ideas into products that not only effectively solve problems, but also evoke emotions, create connections with users, and become an integral part of their lives.
