If you always wanted to write a book but never started, what is the reason? Is it because you lack the time? Are you intimidated by the process? Do you have writing fears?
Writing a book is like eating an elephant; it's a one-bite-at-a-time process. You might only have a few free hours a week. You mightn't be able to write enough words. You may have a general idea but aren't sure how to communicate them. Many reasons might keep you from writing that book, but don't let that hold you back. If you want to write, start slow and see where it takes you.
Remember, you don't have to share your writing with anyone. You don't have to announce you're about to write the next best-seller. You can work on it over months or years. You can start tomorrow and decide it's not for you. But I would recommend starting, even if that means writing a blog for your eyes only. Writing is cathartic. It doesn't have to have a purpose.
Concerns such as grammar, plots, and word counts shouldn't hold you back. I only check my word count when I finish a book. I don't care how many words I write per day. I never know the entire plot when I start a book. I allow it to flow naturally and see where it takes me. I don't worry about grammar because there are apps that can catch a lot, and friends and family will catch the rest.
