My books all carry this theme. They all have darkness to different extents but always with light and with upbeat endings. I read a quote recently that says:
"The Pessimist complains about the wind.
The Optimist expects it to change.
And the Realist adjusts his sails."
I'm a Realist with Optimist leanings. My work reflects that.
