Success Offers No Bargains
As a writer with more than a few manuscripts, published and unpublished, behind me, I know this truth in every cell of my brain. This is why I always encourage those who tell me they're going to write a book when they have the time. I tell them to go for it. They may succeed. If anything, they'll learn it's not as simple as finding some free time to devote to the project.
If they've been particularly condescending in their assumption that free time is all that is needed to write successfully (of course, I'm thinking of one particular individual here), I stand a good chance of being greatly amused when I bump into them in the future. When I ask how the book is coming, I've yet to hear anything but hemming and hawing from those who've actually tried to turn their idea into a book.
More is required than leisure time to successfully write. If you want to write, you must be willing to work hard. Writing is hard on the anatomy, the brain, and the emotions.
"There are no bargains at the counter of success. You must pay full price." That's what Earl Nightingale once said, and it is as true now as it was then.
No worthwhile endeavor is ever as easy as the uninitiated think. If it were, everyone would be doing it and doing it with great success.
