This helps you think outside of the box in a more creative, unusual way and makes it easier to envision a finished product.
You get inspired in new ways
Love enhances all your senses. Smell, touch ,and sight are heightened and the world takes on a new, beautiful glow. Love actually has the power to alter the very way our minds work to process information.
Historically, artists used specific people as muses: modes of artistic and poetic inspiration. Muses were often considered divine, but could also be humans and lovers.
When you're in love, the subject of your affection functions as a muse. Where once you had no source of creativity from which to draw, you're now flooded with an instinctual need to create; memorizing every angle of your lover's face and writing him or her into your every story and poem.
