First, there is Tara Lazar's StoryStorm. Here we read a motivating post each day of the month of January. Generally, we learn ways to see the different ideas all around us from true-for-real authors! It's a great resource for writers or teachers of little writers! You can always access older posts under the StoryStorm tab.
Next is Julie Hedund's 12x12 Writing Challenge. It was initially set up to motivate writers to get that crappy first draft down on paper...one a month. But, it is SO much more. It is a community of kid lit writers who travel the ups and downs of this journey together. We are all at different places in our lives and our careers, but this is for anyone who wants to write picture books for kids.
Then there is the new and improved Aree Chung's StoryTeller Academy! This is the first year for the membership version. The classes that I took last year were phenomenal. This year offers those and aa whole lot more!
Happy Writing in 2019!
