"A great way to write is to overwrite. Write more verses than could be contained in a song. Then take the best of what's there," says Rostam Batmanglij. I cannot agree more: good writers know that the first pass is never the time to decide what to keep and what to leave out. Overwriting will always be faster. Just ask Anne Lamott.

Of course, overwriting for Rostam comes easy because when he's not writing, he's thinking about writing. "I'm always collecting building blocks," he says. "Lots of kernels all the time. I've never truly let go of an idea." 

Rostam's latest album is American Stories.
