I very much agree with what you say. The macrocosm (big order) follows the microcosm (small order) and vice versa. The moment we forget ourselves is the moment we lose power, or maybe, our agency. But when we focus on ourselves, when we give value to the "small things", we realize that, not only do we have more power than we thought, but also that the outside has less power over us than we assumed.
I am a strong advocate of "focus on what I can control and have faith in the rest". And what I've discovered in this regard is that surrendering in terms of any external outcome is often the best way to go about things. Then results matter less, and what we do more.
Yes, a very good motto. :)
