The point of power is always in the present moment.
-Louise L. Hay
In grief, we may tend to worry about what happened in the past or what awaits us in the future. By doing so, we worry about things we can no longer change and things that we cannot foresee. The present moment, the Now, that is where our focus should lie. We can only embrace and act in the present.
In the moment of struggling to figure out what to do in the future, do what you can in the Now. If the only thing you can do at present is make a sandwich to feed yourself, your spouse, sibling, or child, then make a sandwich. Every act, no matter how small it seems, is a step forward in your healing.
