Strength and perseverance are silent. They have no need of your validation. They are not interested in whether you notice them or not. They simply lie in wait, ready to rise to the occasion when life demands they stand and deliver. It is not the person preening and beating their chest all day with loud trumpets of their own magnificence you need fear. They are working to distract you from their own insecurities.
It is the person steady, quiet, consistent and patient that you need to keep your eyes on. They don't care about your perception. They don't waste their time with illusion. They are focused solely on their desired outcomes. And they know they possess all they need to achieve them. Their spiritual resources are endless.
