You forget tasks, appointments, and important details constantly
A notebook or notes app, phone reminders, a whiteboard (optional)
ADHD working memory is like a whiteboard that gets wiped every few minutes. Externalising everything to a reliable system means you stop losing important information. The brain is freed from trying to hold onto things and can focus on actually doing them instead.
Designed for adults. The simpler the system, the more likely you are to use it consistently.
A parent who'd been forgetting school forms, appointments, and bills bought a £3 notebook and wrote down everything the moment it entered their head. Within two weeks, the forgotten-task anxiety that had been constant for years started to lift.
