Don’t follow a map, don’t read anything, don’t ask, don’t look at other people, don’t try to make it worthwhile, and don’t try to “get it.” Just start walking, glancing as you are moving quickly along. Don’t feel bad if nothing “speaks” to you; just keep moving on. It might be in the 10th room, but there will be some work that will grab your attention. Stop there and just look at it. And look until you feel you are ready to move on. That is it.
You will find that experience lights a spark. In a nutshell, it is a personal experience of art. After that you might be interested to research art, movements, and artists. But none of that replaces the unique spark that speaks to you.
