There is a practice in the meditative tradition called “aimless wandering”. It is a form of walking meditation but instead of focusing on our body walking, we connect with our sense perceptions as directly as possible.
It works by setting out for a period of time (you can start with 20-30 minutes if you like) and simply ramble around without any specific agenda. This will be really hard for some of us and maybe too easy for others! Try it.
When something grabs your attention you can linger for a moment but try not to capture anything or manipulate your experience in any way.
Aimless wandering is a key component of the creative process and goes along with the sandbox idea. We’re loosening up our moorings and leaving space for something new to arise.
