Your path as a writer has a beginning, middle, and end. It isn't want defines you. It's simply a set of rules you've put upon yourself to be met.
Write your first novel.
Attempt not to humiliate yourself.
Write another novel.
Without those beginning, middle, and ends, there gives you no goals and no hope. If you have an open slate chances are you'll be that procrastinator we all love to hate that creeps in and takes over your writing life.
Part of a writers life is to be dedicated. JK Rowling didn't become a success because she half-assed the Harry Potter Series and only wrote four novels. No, she finished all seven, no matter how many blood, sweat, and tears went into it she knew she had to complete it. It was her goal, the end of one project so she could start the beginning of another.
Are we better at one stage? I'd say in the game of writer life I'm better at the beginning. It's that energy you get when you feel that the whole world has your back, you're going to be successful, and the end is going to zip by so fast you'll be waving all the way from project three. It's tough to pull yourself out of the beginning because it's so damn fun. There are no responsibilities. Just you and your pen taking on the world.
The same applies to the writing itself. A beginning, middle, and end. After all, if you never set the goal you'll just be the so-called-writer who lives in their grandparents basement still working on the comic book story you started when you were seven.
Don't be the so-called-writer. Set some goals. Decide where you're better at and strive to push through the one your the worst at.
In your writer life or writing in general, where do you stand? What's the most difficult stage for you?
