What's the metaphysical symbolism of eye strain?
You are looking at a disproportionate amount of negative events. Find something each day that inspires you.
Does that include internal 'events', for example, focusing on limitation?
Yes. Most certainly.
We increase what we focus on. When we focus on lack, we become impoverished. When we focus on the confusion and the dysfunction of others around us, our environment becomes chaotic.
When we replace focusing on the negativity of others with a focus on their contribution and achievement, we become inspired.
