There's nothing more attractive than a man who knows what he wants. And let's face it, if you don't have goals, what do you have to look forward to in life? The absence of any dreams or future goals indicates to women that you're looking to them for direction, which is not a big turn on for most of us. Women don't want to be your mother, they want a partner. A partner who will participate in shared goals as a couple.
When we say 'goals' we don't mean that you have to be training for a marathon or starting a very ambitious business (though those certainly count). It can be something as small as loving to set aside time to write every day or hoping to own a home one day. Do you want a family? That counts as a goal, too!
