Often, people approach me to say they'd like to write a book but they just don't have the time. Well, we've all got only 24 hours in a day but it's how we spend it that counts I know writers who get up at 4:00am to write and I know others who get in what writing they can while their babies are napping. There are writers who take years and years to write and then there are those who take a couple months off from working to thump out a manuscript.
What would-be writers are intimidated by, I think, is the idea that their first draft has to be perfect and ready for publication. Trust me, it doesn't! What's important is you getting the words down - fine-tuning the plot and fleshing out the characters can come later. You can't edit and polish a blank paper but you can definitely work on your rough draft!
So, make the time! If this is your dream, don't let it pass you by. A page a day will net you a manuscript by the end of the year. Let 2012 be it for you!
