I have a tendency to worry about what I should be doing, what I need to do next, and what I should have already done. What if it is sometimes best to just do nothing? To let breath pass through my body? To allow the minutes to tick by unfilled? To see what I see without actively looking for it? In short, what if it is sometimes best to let life happen to me?
If you tend towards doing and need time to practice non-doing, then I encourage you to try out a restorative yoga practice sometime. It is a conscious choice to do nothing, if only for a short while.
