TRICK 02.
—Whether it's poetry, a short story, or adding to a novel, write something each day, so it gets easier for you to get into a groove when you eventually get stuck with writers plot.

Whatever it is, always put pen to paper, or fingers to keyboard, or thumbs to screen. Writing constantly helps you improve — daydreaming will not.
