Kristi Holl, I think, has some good ideas.  Things I don't always think about.  And even if you don't write for children or you don't necessarily write book, I like the Seven Essential Habits of a Working Writer she mentions by Jim Denney.  You can apply it to anything you want to do on your own.

• Write Daily (Or paint or sew or brainstorm)
• Cultivate the Art of Solitude Amid Distractions (Figure out how to work with children pulling on your shirt or spilling Koolaid on the carpet.)
• Write Quickly and With Intensity (Self explanatory)
• Set Ambitious But Achievable Goals (Again, self explanatory)
• Focus!
• Finish What You Start and Submit What You Finish (Even if you think it's not your best job, finish it anyway.)
• Believe You Can  (Always excellent advice.)
