No time to write? Of course you have. Everyone has moments throughout the day when you could be writing – if you're prepared.
Writing in moments takes a little planning. Firstly, you need to make your current writing projects portable in some way. Many writers write in paper notebooks. Others print out their work, and stuff the typescript into a folder or a bag, then write on the back of the typescript and on loose-leaf paper. Some writers prefer laptop computers.
Next, decide what you're going to work on. If you don’t plan to work on Project X or Project Y, you'll spend five minutes doodling. Take along a couple of projects. If you don't feel like working on an article, you may feel like working on a short story. Some writers simply designate "spare" writing as brainstorming time, or journaling time.
I take along any project which I seem to have stalled on. I find that writing away from my office frees me up enough so that I can relax and find fresh angles in my work.
