Like many things, saving is a habit. To build positive habits, there are a few things you can do. First, set yourself a goal: how much do you want to save each week? How much do you want to have at the end of the year? Second, tell others. We know that positive habits are reinforced by social norms, so telling others will make you more likely to reach your target. And third, don't worry if sometimes you don't always save what you expect. Being gentle on yourself is also important. There is always next time.
