Emotions are critical in most novels, but writing them can sometimes be a challenge.
Describing outward emotions can often sound forced because people in the moment feeling those emotions aren't usually thinking, "I just want to stare deeply into his eyes." They're thinking about the color, the way the other person makes their heart race, how time seems to stop when their gazes meet. It's the effect of that deep gazing that's on their minds, not the actual gazing part.
Let's say you're writing a situation that requires an emotional response. Instead of looking at the character who's about to become emotional in some way, try going inside her head and thinking about what that person would feel.
