From good intention to a specific step

Choose the moment when you’ll get started

“I’ll waste less” points you in the right direction, but doesn’t say when or what to do. Try turning it into an approach linked to an everyday situation: when I start making my shopping list, I’ll check the fridge first. The cue is a specific event, and the action is something you can observe. Later, this makes it easier to tell whether the problem was remembering, carrying out the action or choosing the approach itself.

In a 2010 study, Lally and colleagues followed volunteers who repeated a chosen activity related to eating, drinking or exercise in the same context. The behaviour they tracked became more automatic with repetition, although the pattern varied between people. The research relied on self-reports and didn’t test every kind of habit. It doesn’t establish a universal timeline or guarantee that green habits will work; it provides a basis for trying a regular link between a situation and an action.

Choose a cue that really occurs before the action you need to take. A reminder after you’ve paid won’t help you check what you have before shopping. If your work schedule is irregular, an event may work better than a specific time. For example: after my last work task, I’ll check which devices I can safely switch off.

Start by testing one clear link. If you attach a long list of tasks to one event, it’s harder to see which part isn’t working. After trying it a few times, you can expand or shorten the approach, or move it to a more suitable moment. A good plan needs to fit the way your day actually unfolds.
