Humans are driven by habits. Those habits are driven by triggers. This setup is a genius invention to save brainpower - and it’s a nightmare when your triggers are removed or reshuffled unexpectedly. No trigger, no habit (so not really your fault) The things you do regularly and automatically are usually triggered by a social cue, a localization, or by a specific previous event. That’s why it’s so easy to forget working out while traveling and why you tend to forget to take a lunch break when working on your personal projects at home. It’s also the reason why you get up to walk 250 steps when your Fitbit beeps at you for not moving enough.
