To understand the logic behind this model, lets go backward to see where it comes from. Lets say you want to study to play the piano:

1. First you need to ask yourself if you are interested. If not, there is no point to study. You would otherwise just waste your time as your attention for things you study without interest is close to zero.
2. To be interested you need to have a feeling for the subject, or in this case music. You must like either the act of playing the piano or enjoy listen to the music itself. Without a feeling for something there cannot be interest for it.
3. To have a feeling for something you must engage with the matter. In case of the piano that can be achieved by going to a concert, listening to an amazing piano player on youtube or even better meeting people who make music themselves.
