What so many people get wrong is confusing attraction with love.
A young man has just seen a young lady and jumps into conclusion; oh mine! "This lady is beautiful, she's just wonderful. Check out here legs, the way she walks, the way she talks, wow! She's beauty-personified. I knew i had found love. I just can't wait to get her, it would really be wonderful." Quite romantic, is it? But as romantic as these expressions sound, they are very untrue. It is just a fleeting passion. Why? Because you can't really love someone you don't know. In other words, what has been experienced by this young man is simple attraction.
