Challenging can mean difficult: a difficult time in life or a tough place to be. Or it can refer to a deliberately provocative deep question that a coach might ask that stretches your self-view. It might describe a lifestyle where the status quo always seems in the way, or it could be a way to approach boundaries and limits. What does it mean to you?
Panoramas are vast viewscapes. Making a photographic panorama involves stitching together several individual views, and sometimes even several view points. So imagine your whole life as an artistic masterpiece that stretches the entire wall of a gallery. Could you ever step back far enough to take in the whole thing? What does it look like from other viewpoints? A panorama could also be a time period or situation. Perhaps your current panorama is restricting. What's in your panorama? What colours, moods, situations and choices are there? Does it need challenging?
