Check out the Writing Excuses podcast (http://www.writingexcuses.com/).

They're all published and commercially successful genre fiction authors, and the podcast is consistently high on quality and low on BS, unlike at many other sites offering writing tips, tricks, strategies and advice.

All the episodes are ~15 minutes long, and most have a writing prompt or exercise at the end that can be completed in roughly the same amount of time.

Block out 30-45 minutes of time in the morning to listen to an episode and write on the prompt.
