Write daily

I have found that the easiest way to achieve any writing goal is to work on it a little bit each day. Instead of committing to five hour chunks of time a few days a week, I prefer to spend twenty minutes here and an hour there polishing my work. Doing this, I've never felt obligated to stick with a story that I'm not feeling creative about, and I've never felt forced to write beyond what feel is good writing.

Instead of forcing yourself to take on huge chunks of a plot, try writing a little bit every day. You may find that your daily activities in your "normal" life fuel the realism that your characters face, and add to your story.
