Most of Tanya's experience in writing was from her time in college. Researching and writing evidence-based papers. In that time, she learned how to write concisely, often about complex subjects. Focusing on the information that needed to be included and the best way to organize and present that information, without boring herself or her reader into a complete stupor(hopefully).
This isn't very different from the writing experience she has had later in life. She has a blog, she writes inordinate amounts of correspondence, and for fun, she sometimes composes letters to the editor on issues where ranting to her friends and family doesn't feel sufficient enough.
Tanya's focus in school was the sciences. She was best in Psychology, Physiology, and anything that involved copious amounts of research. However, she would also say that she is well versed in English Literature and Music. And, being the child of a farmer and a soil scientist, she knows a lot about Agriculture and Environmental Sciences.
