Comment below on a mistake you've made in your publishing journey. My losses are your gains, we can all learn from each other!
1.) I should have insisted on CMYK with each illustrator throughout the project.
Even though I mention that I need CMYK from the outset of each book project and include it in the brief, somehow CMYK sneaks in. This is, ultimately, my fault. Now, my observant eyes notice when the colors are not CMYK. RGB is prettier on screen and, perhaps, that's why illustrators send them over that way.
2.) Hired the wrong formatter/designer
If you search my name and go back to one of the very first posts I made, you'll find pictures of my very first book I wrote with my son, Kobe. The designer I hired didn't own the proper applications to transfer my high resolution illustrations and format the book properly. You'll see that even though I requested bleed, this particular designer still left white trims in the book and the quality was poor because the illustrations were phoshopped into the mobi/pdf files.Now, I've been lucky to find not just one but two very qualified designer/formatters.
3.) Failure to blog/journal my journey
My oldest son, Mikey, is writing a book. I love that. I want to build a reference point for him so that he can see there are days I feel discouraged and a failure. I want him to see and experience the excitement and the successes so I've started today. I just wished I had done it sooner. I hope one day Kobe and Jojo will grow up to read it, too, perhaps on their own publishing journeys. There's a RSS feed you can sign up to get new posts. I plan to write at least every few days. This journal will help me celebrate every little success I may experience. Since, I tend to be a bit of a workaholic, I've learned that if I don't reflect on my journey, I become drained.
