Have you ever gotten your pupils dilated at the eye doctor?
It starts with an unpleasant liquid being dropped into your eyes, and it ends with sensitivity to light and temporary farsightedness.
As hard as you try to focus on something up close, you can’t.
It’s frustrating, but it’s ok because you know it will pass.
We can apply that to solving problems.
You might not have a solution in front of you, and no matter how hard you try to focus, you can’t seem to get anywhere.
Take a break, and come back later.
