I really like this picture, taken by a photographer named David duChemin. He captured it somewhere in Tunisia. At first glance, it seems like a well-composed study of architecture and tradition. You perhaps admire the intricate door, the woman cloaked in white, the symmetrical beauty of Tunisia's ornamental design. But then… you notice the cat. Almost camouflaged against the sunlit stone. That detail (subtle and easily missed) transforms the image.
Of course, we can't help but think that the photographer was lucky to be there to capture such a moment, but I think this is more than luck. A person who is serious about their craft is prepared for luck, so to speak.... Serious photographers spend years polishing their technical skills (he still had to frame the shot well and know how to use the camera), but they are always waiting, always ready for luck to come. Great photographers show up, wait, remain open to serendipity, and then compose and execute. Creativity thrives in this liminal space, between design and accident. Between what you plan and what unfolds.
And this brings me to a practical guideline. Since things in life are constantly unfolding, what you decide to put inside a frame (a page in a document, a slide in a presentation, or a photograph) can go beyond its edges. Both the woman and the cat are leaving the frame. Perhaps they were not meant to be captured. Those of you who are cat owners already know the moody behavior they often have. This photo beautifully challenges what is meant to be inside the frame and what can exist just outside it.
As a guideline, consider creating content that sometimes "bleeds" beyond its edges. Life often does not fit so neatly inside one frame. In real life, something interrupts it or escapes the frame. So, consider leaving the edges of your frame open. Don't resolve everything, let something escape.
