'A writer writes, always!' Write for ANY reason, just write! I believe we are special tools for the Creative Conscience, and learning to hear that voice begins by just articulating or activating, and staying attuned to what happens. Put the pen to paper - or fingers to the keyboard - see where it takes you, and apply those results to your puddle of wisdom... swirl it, dip your toes, taste the sweet and bitter. Yes - just DO it!
