This is why hands on exercise is necessary. This is why building
something out of the tutorial is required. This is why knowing answers
of the back question of the chapter isn't all.
If you want to learn a subject, a tool or a skill you have to be more
wrong than right.
Being wrong forces you to find the answers, it prods you to explore
and go beyond. And that is where you truly learn the subject or skill.
