When trying to make progress toward a goal, sometimes it is helpful to pretend that the goal has been achieved (even if the goal is just one tiny step) and act in that way. At least for a short time.

For example, you have a goal of being more assertive at work, or being more patient with the kids. Act that way in at least one situation.

Then observe the positive differences in your behavior and mood. Let your small successes in that area guide you as you develop your new habits.
