Hibbert attributed her large output to her regular working habits. She described herself as a compulsive writer and would write all seven days in the week. She started every morning at the typewriter on her desk, usually completing five thousand words by lunchtime. Though writing stimulated her, she found the typewriter to be a physical strain. She devoted five hours every day to her writing, in addition to the time that it took her to proof-read her draft and conduct research. In the afternoon, she would personally answer all the fan mail she received. She would also spend time at Kensington Central Library. In the evening, she played chess if she could find an opponent or attended social engagements.
