One is quality.
Other is a tendency to not move or do nothing.
Stillness brings serenity.
Inertia and inaction breed anxiety and fear.
Stillness is worth cultivating and practicing.
Inaction is something to avoid and abhor.
Stillness becomes easy when we stop fighting chaos and embrace it.
Inertia needs our will and effort to get us into motion.
When we move, we shake off the fear, anxiety, and ripples of unknown failure.
Then we meet growth.
