Things beget things — like themselves. You know:
Dogs beget dogs.
Oranges beget oranges.
Persimmons beget persimmons.
Kindness begets kindness — when you do something nice for someone, they want to return in kind.
The same is true for writing. When you spend time writing, you want to spend more time writing.
When you write one day and then the next and then the next; well, the next day you wake up with a great blog post idea or the answer to your character’s dilemma or the location of your character’s trauma or … you get the idea.
Writing begets writing.
Do you want to write? Write, then. Then you’ll write more. Then you’ll want to write more. Then you’ll write again.
It’s really fun. I just love it. I’m sure I’m not alone in that feeling.
