I read this book very quickly (1.5 hours) but it was chock full of good practical advice on the creative process. I highly recommend it to anyone - because as Austin Kleon states we are all creators no matter the job that we are doing.... and human beings are interested in knowing about how you do what it is that you do.
Other great advice is to always acknowledge your sources, once you have made it then start over and create something new again - don't just stay with the familiar.
Be humble, share yourself, your work, your process.
