Whenever you have a thought you want to remember, write it down right then (obviously not when you're driving etc). We have so many devices at our fingertips that we can write notes, into which we can dictate, or we can even carry these tiny pads around to take notes. On your computer, have one folder in which to transfer all these materials, whether it's a photo, a scan of a scrap of paper, or a note. Or, even put an open-top box in your office, your bedroom, into which you drop this stuff. Each week first thing in the morning on a designated day, TAKE care to put all this stuff into that computer or organize, flesh out, whatever scraps of notes you have in your box. Most importantly and most obviously, whatever you are writing has to be something of which you are absolutely in love. You have to be so passionate about it, such that for instance, it gets you through 4 months of formatting-for-print issues. So much that it gets you through over 2 years of rejections from publishing companies. Your subject has to be something to which you can stick for a LONG time.
