When you focus on something you are thankful for, the effect is instant. It immediately shifts you from a lack state (regrets, worries about the future, the feeling of being behind) and puts you into a have state (what is going right, what progress you are making, what potential exists in this moment). It reminds you of all the resources, all the assets, all the skills you have at your disposal—so you can use them to more easily do what matters most.
