"Don't leave your comfort zone. Make your comfort zone bigger." This really resonated. If you think of your discomfort as the work of making your comfort zone bigger, it's less intense. A meta-story can help.

This line reminds me of the concept of the zone of proximal development (ZPD) [1]. You can make your comfort zone bigger by intentionally spending time at the edges of what is comfortable.
