We learn things in two different ways: by doing things ourselves and by listening to what others tell us. The stuff we learn by doing things stays in our minds for a long time. It's better than the stuff we learn just by listening to instructions. When we learn from instructions, we have to work hard to remember and repeat those instructions. But the things we learn from actually doing stuff are easier to understand. They get stuck in our minds. We can remember and use them whenever we need to. This way, we can keep the lessons we learn. The knowledge we get from experience is deep, accurate, and complete. No amount of lessons in a classroom or talks from really good teachers can replace the knowledge we get from doing things ourselves. We can truly understand something if we get involved in the whole process of doing it. So, it's right to say that experience is the best teacher.
