Thinking about what to write can sometimes seem hopeless as you stare at a blank computer screen. You've got writer's block - again!
I can't say it enough. Establish a routine. Use the same routine as you start to write each and every day. It's not enough to set the same time aside each day. Do something to successfully transition into your routine. Turn on your favorite song, get a cup of coffee and then sit down to write.
Use free writing to get started if you have to. Once the ideas begin to flow, you can just pile them up, sort them out, and refine them later.
At the end of every session, take a little time to give yourself an assignment for tomorrow - while you're still in a creative mood. When you open up that draft the next day, you won't be starting from ground zero.
When you're away from your work area doing something else - jot down ideas as they come to you and put them in a folder next to your computer. You'll be in a less stressed frame of mind when you're cooking or playing golf. (Just a couple of examples. 
). But it's at times like these that good ideas pop into our head. Write them down. Later, put them in that idea file next to your computer.
Ideas and inspiration can come at the weirdest times. Sometimes I wake up from a dream and write a note in the middle of the night. Some of them seem silly in the morning - but a lot of them turn out to be good writing subjects. Inspiration is everywhere.
