My uncle worked as a contractor, and I studied technology with him for a month. He told me to move bricks with cement every day instead of teaching me to draw.

Any expert starts with moving bricks with mud. Pay attention to what the masters do, and get started slowly. It's impossible to teach you to apply cement first and then brick like a school teacher. If you are crooked, you are not afraid that we will push the wall again. In this case, you can't even get paid. Understand, after all, this is society.
