I think writing really helps you heal yourself. I think if you write long enough, you will be a healthy person. That is, if you write what you need to write, as opposed to what will make money, or what will make fame.
Write the story you want to write, not the story that you think will sell. It may sound offensive to some, and I’m sorry for that, but anyone and I mean anyone could have written Twilight. Anyone can write what’s popular. Anyone can write stories with no heart, no fire. It’s not that difficult. But it takes a true craftsman to bleed onto the page. It takes an artist to write the story of their heart and worry about publication later. If you’re in the writing game to make a quick buck, I’m sorry, but you are so in the wrong business. Rowling and Collins and yes, Myer, hit the lotto. Their successes were the exception, not the rule. You’re going to be spending a great deal of time with your story, with your characters, if your intention is publishing. You’d better be comfortable around them. You’d better be passionate about the story you’re writing. If you’re not, then you’re in for a very tedious, painful road ahead. Write what you love and I promise, that book will love you right back.
