Your job is to collect ideas. The best way to collect ideas is to read. Read, read, read, read, read. Read the newspaper. Read the weather. Read the signs on the road. Read the faces of strangers. The more you read, the more you can choose to be influenced by.
Identify one writer you really love. Find everything they’ve ever written. Then find out what they read. And read all of that. Climb up your own family tree of writers.
Steal things and save them for later. Carry around a sketchpad. Write in your books. Tear things out of magazines and collage them in your scrapbook.
