We’re never too old to become a best-selling author. But there will be many bumps along the way. There will good days and there will be bad days. But our skill improves with the 3 imperatives of writing: read to learn from other authors, develop your process, and write. And write. And write. Writing about people requires a study of human nature, an understanding of what your character would do next if s/he were real instead of fiction.
There are seasons in the process. Spring bursting with hope. Summer filled with inspired writing. A fall in leaves and temperatures and confidence and the deep chill of winter. And then the spring of hope again and a summer of fruition.
The secret to success: Persevere.
To quote Stuart Horwitz,
Keep your ears tuned for what resonates, keep looking for inspiration, and give your project room to surprise and challenge you.
