“Two chemicals called actin and myosin evolved eons ago to allow the muscles in insect wings to contract and relax. Thus, insects learned to fly. When one of those paired molecules are absent, wings will grow but they cannot flap and are therefore useless. Today, the same two proteins are responsible for the beating of the human heart, and when one is absent, the person’s heartbeat is inefficient and weak, ultimately leading to heart failure.Again, science marvels at the way molecules adapt over millions of years, but isn’t there a deeper intent? In our hearts, we feel the impulse to fly, to break free of boundaries. Isn’t that the same impulse nature expressed when insects began to take flight? The prolactin that generates milk in a mother’s breast is unchanged from the prolactin that sends salmon upstream to breed, enabling them to cross from saltwater to fresh.”

“You've a soul for a compass, and a heart for a pair of wings...Why walk when you can fly?”

“Our treasure lies in the beehive of our knowledge. We are perpetually on the way thither, being by nature winged insects and honey gatherers of the mind.”

“Looking at a sea bird flapping its wings against the full moon I wish I could grow wings and fly away from everything and be free. I wish I could lose myself in the vast ocean and float away from all this pain in my heart.”

“You love someone, you open yourself up to suffering, that’s the sad truth. Maybe they’ll break your heart, maybe you’ll break their heart and never be able to look at yourself in the same way. Those are the risks. You see two people and you think they belong together, but nothing happens. The thought of losing so much control over personal happiness is unbearable. That’s the burden. Like wings, they have weight, we feel that weight on our backs, but they are a burden that lifts us. Burdens that allow us to fly.”

“As a child, he'd found a butterfly emerging from a cocoon. He'd tried to help it by prying open the husk to set the insect free. It had lain in the sun, beating its wings as they dried, but had never flown and soon died. His grandmother explained the butterfly needed to go through the difficulty of freeing itself in order to have the strength to fly.”
