When I told S that I am struggling because I know that something good lies ahead of my struggle, I used the analogy of a caterpillar struggling out of its cocoon to become a butterfly.

S said, "Why do you think the caterpillar struggles?"
I replied, "Like I said, it's becoming a butterfly!"
S then offers his insightful opinion.

"I don't think the caterpillar knows it is going to become a butterfly. I believe it is struggling because its uncomfortable."
