Create a scheduled time to write. Make it a habit. Most writers find this helps them compile the manuscript they have put off writing. It can be a daily schedule of at least 30 minutes to an hour. One of my writer friends maintains a schedule of writing from 10:30 am to 6 pm, allowing for eating breaks and stretches. She is consistently completing book after book. Once she finishes one , she is sending them to a publisher and beginning a new one. She has 9 published books with 3 ready to submit, This constancy has lead to increased strength in her writing experience, Flex your literary muscle and you too will gain publishable clout even you will recognize as you read over the text you compiled.
If you have an outside job, write before or after you head to work, Make time to write.
