One key piece of advice when it comes to writing is to never give up. This is the point Carol Despeaux makes at onewildword.com. I agree and I like to tell myself to "Just keep putting words on the page". If I just keep putting words on the page, stuff gets written. I also remind myself that the only reason I write is because I enjoy writing and I need to write. If I write for any other reason I usually don't get it done.
What do you think?
