Every Wednesday night I take my three teens and one elementary child to church. The little one goes to AWANA clubs while my older three go to youth service. Our youth minister Scott Buck taught about the book of Ecclesiastes, King Solomon's account of his exploration of the meaning of life. No. It's not 42.
During his sermon, Scott emphasized a verse in the text that really struck home with me as a writer:
One who watches the wind will not sow, and the one who looks at the clouds will not reap. Ecclesiastes 11:4
Yep. This verse is about laziness. If you are sitting there thinking about writing that novel one day but have never put pen to paper or started typing away on the keys, you have not "sown" any kind of seed that might grow into a novel. Even the smallest effort may turn into something workable, but if you sit around "look[ing] at the clouds" all day, you won't get anything done.
We can tell ourselves during our days of unproductive dreaming that we are planning our novel, but this could stretch into days and weeks of inactivity that really doesn't amount to anything. Inactivity is never really going to allow you to "reap" anything at all.
So get busy. Stop daydreaming and daydream on paper or on a word-processing file. Anything is better than nothing.
