Of all the writing tips and advice a writer will receive in his/her lifetime, this, in my opinion, is the most important:
There is no one right way to writing a book. Some writers intricately plot their stories, some fly by the seat of their pants. Some interview characters; some do detailed charts about goal, motivation and conflict. Some write daily; Some write when they can. Some write crappy first drafts; some need to be more precise in the words they put on the page. Some write 3,000-5,000 words day; some can only master 1500.
How you get the book written doesn’t matter. Your writing process will be as unique as you are. There is no magic solution, no right way or wrong way to getting a book done.
Character arcs, plot, conflict – these are all important elements that make a successful book. But they come second to actually getting the words on the page in the first place. As Nora Roberts famously said, you can’t fix a blank page.
So stop looking for the “Best Way” to write a book. Write it your way
