Light at the end of the tunnel!
Wherever my story takes me, however dark and difficult the theme, there is always some hope and redemption, not because readers like happy endings, but because I am an optimist at heart. I know the sun will rise in the morning, that there is a light at the end of every tunnel.
When a train goes through a tunnel and it gets dark, you don't throw away the ticket and jump off. You sit still and trust the engineer.
Corrie Ten Boom
No matter what you're going through, there's a light at the end of the tunnel and it may seem hard to get to it but you can do it and just keep working towards it and you'll find the positive side of things.
