In 2007, after facing my 44th rejection, a colleague recommended that I meet a published novelist. That novelist was Hilary Mantel, and over the next 15 years, I had the incredible opportunity to learn from her insights and experiences.

At that time, I was an aspiring author with a manuscript that had been rejected by 43 literary agents. Back then, you had to print and mail your submissions, which included personalized cover letters, three chapters, a synopsis, and a self-addressed envelope for the inevitable rejection slip. Despite the odds, I remained hopeful. The 44th agent I contacted even requested an exclusive read of my manuscript, which made me believe that this could be my big break.

However, weeks later, I received yet another rejection, this time accompanied by a polite cover letter thanking me for my submission. I opened the package just before heading to work, and when I arrived, I found it hard to hold back my tears. At 28, I felt like my dream of becoming a published author had come crashing down. A sympathetic colleague noticed my distress and asked what was wrong. After I shared my disappointment, she kindly offered to introduce me to a novelist she knew, thinking I could gain some valuable advice.

That novelist was Hilary Mantel.

At the time, Hilary was already a renowned author known for her fiction and memoirs, although she had yet to publish “Wolf Hall,” a work that would eventually earn her immense acclaim, including two Booker Prizes and adaptations for stage and television.

Through my correspondence with Hilary, I discovered a calming voice that helped me gain perspective. Our 15-year friendship was filled with both laughter and profound conversations, and I cherished every moment.

As we approach the autumnal equinox on September 22, which coincides with the second anniversary of Hilary’s passing, I feel a sense of reflection and would like to share the lessons I learned from her.

**Know Your Ending and Write Towards It**
There’s an ongoing debate among writers about the merits of planning versus spontaneity. While both approaches have advantages and pitfalls—over-planning can render your work mechanical, while improvisation can lead to chaos—finding a middle ground is key. Hilary wrote the conclusion of “The Mirror and the Light” well before finishing the book. Having a clear ending can guide you while still allowing for creative exploration.

**Write Every Day**
One day, I asked Hilary if she wrote daily. “Yes,” she replied. I felt embarrassed that I didn’t, but she gifted me a week-to-view diary for Christmas, which inspired me to commit to daily writing. I found that mornings were the best time for me to jot down a few lines, and nearly seven years later, I still write daily, often filling an A4 page with my reflections. This habit has greatly benefited my well-being and writing discipline.

**Greatness and Gentleness Can Co-Exist**
Hilary was incredibly gentle and deeply cared about her readers. She made sure her storytelling was rewarding without being overly simplistic. She engaged warmly with audiences and appreciated their support. Throughout her career, Hilary uplifted other writers, providing endorsements that significantly impacted their success. Even during my own challenges, including battling cancer in my 30s, Hilary continued to reach out, believing in me as a writer when I struggled to believe in myself.

**Back Yourself**
Hilary taught me that artists face two types of success—internal and external. These can sometimes be at odds, with the projects we are most passionate about not always aligning with commercial viability. As a writer, it’s vital to have faith in your vision.

**Quality Over Quantity**
The length of “The Mirror and the Light” raised some eyebrows, yet it showcased Hilary’s natural, flowing voice. Her writing captivated readers, making every page feel purposeful. One of my favorites of hers, “Terminus,” is just 1,690 words long, yet it encapsulates her creative essence—concise and meaningful.

**We Create, Not Reproduce, the Past**
In her BBC Radio 4 Reith Lectures, Hilary offered invaluable insights on writing historical fiction, expressing her commitment to historical accuracy while exploring the thoughts and feelings of her characters. Transforming historical events into rich narratives often hinges on perspective.

**Ideas Have Their Own Timelines**
Hilary was in her 50s and had numerous works published before achieving “overnight” success with the “Wolf Hall” trilogy. She believed life experiences are crucial to effective writing and that we often need patience to bring the right project to fruition.

I frequently discuss the discipline required in novel writing with new authors, and I’ve come to understand that sometimes, it takes more strength to wait for the right moment rather than forcing a project before its time.

While Hilary never had the chance to read my completed second novel, “Pathways,” I am thankful that our initial meeting—sparked by my earlier manuscript—set me on this fulfilling journey.
