Rather than causing mental atrophy, AI can be a 'prosthesis for your attention.' It can actively combat the natural human tendency to forget by scheduling spaced repetitions, surfacing contradictions, and prompting retrieval. This enhances cognition instead of merely outsourcing it.

Memory doesn't work like a linear filing system. It's stored in associative patterns based on themes and emotions. When one memory is activated, it can trigger a cascade of thematically connected memories, regardless of when they occurred, explaining why a current event can surface multiple similar past experiences.

While time tracking is for management, its surprising long-term benefit is creating a detailed journal. By capturing context around events, it creates richer memories. This act of savoring makes time feel more expansive, combatting the feeling of "where did the time go?"

Salient emotional events feel vivid and true, boosting our confidence in the memory. However, this confidence is often misleading. Each time we recall and "reconstruct" these memories, we create more opportunities for errors to creep in, making them factually less reliable than we believe.

We don't just forget our thoughts; we forget that we've forgotten them. This cognitive bias, like an amnesiac shocked by his aging reflection, causes us to overvalue our current anxieties, failing to recognize they will likely fade into oblivion like countless thoughts before.

Instead of treating notebooks as a sacred archive, use them as a disposable tool for offloading short-term memory. This approach, focusing on capturing ideas in the moment and stream-of-consciousness writing, reduces the pressure to be perfect and increases daily utility.

The brain doesn't strive for objective, verbatim recall. Instead, it constantly updates and modifies memories, infusing them with emotional context and takeaways. This process isn't a bug; its purpose is to create useful models to guide future decisions and ensure survival.

Technology doesn't change the brain's fundamental mechanism for memory. Instead, it acts as an external tool that allows us to strategically choose what to remember, freeing up limited attentional resources. We've simply offloaded rote memorization (like phone numbers) to focus our mental bandwidth elsewhere.

While repetition is crucial for skill mastery, the brain eventually stops recording familiar experiences to conserve energy. This neurological efficiency causes our perception of time to speed up as we age. To counteract this, one must intentionally introduce new challenges to keep the brain actively creating new memories.
