Patience in a man will never ever go unappreciated. Patience when we take too long to get ready, patience when we're stressed and need to vent, patience when we can't make a decision, and basically patience any time we're having a 'moment' is one of the most attractive qualities you can possess. Men with short tempers and no understanding won't last in a happy relationship with a woman for very long.
If we're being real, patience is something both members of a romantic relationship need. We're not the exact same people, and understanding that is the key to remaining patient with your significant other. When you're getting frustrated waiting around for her to get ready, remember that she probably controls herself when you're playing video games. In some ways, patience is absolutely crucial for a working relationship.
