As I’m writing this article, I’m about to post only my 13th cooking Instagram reel in the past 15 months, which is the same amount of reels I posted in the four months prior to that (update: here it is ). My posting has slowed down quite substantially. Why this slowdown happened has been knocking around inside my head for a while now, so I’ve organised my thoughts, and wanted to share some…
Most people, if you asked them, would agree that Proper Planning Prevents Poor Performance.

Once learned, however, it is very simple to do in practice. What usually…
Abraham Maslow, creator of the most famous pyramid outside of Egypt, once said that “it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.” This is known as the law of the instrument, and it refers to the human tendency to over-rely on a familiar tool, specifically in cases where it is not appropriate.

The crickets had just started to chirp peacefully outside the dining room window as I lay on the couch, knees up, watching something on my laptop. I can’t remember exactly what it was — maybe Kyrie Irving highlights — but I know that I wasn’t engrossed. Whatever I was watching was just filling space, occupying time until bedtime came around.
