Carrying a small notebook with you always, in your pocket or purse, along with a reliable ballpoint pen will enable you to jot down spot observations and quick character sketches before the first sharp impressions fade away. You'll need all kinds of story actors, because even picture books can include a wide range of ages, relationships, occupations, and nationalities. Learn to observe and analyze swiftly, wherever you are.
Loving your subject, you will write about it with the spontaneity and enthusiasm that will transmit itself to your reader. Loving your reader, you will respect him and want to please him. You will not write down to him. You will take infinite pains with your work. You will write well. And if you write well, you will get published.
Don't have conversations taking place in empty space. Weave in background details of where the action (dialogue is a form of "action") is taking place. Don't have invisible people talking, either. Let the reader see them as they speak - their facial expressions and gestures. And by all means "cue" the speeches to the speakers.
