Valentine's Day is the most romantic day of the year. Use this day to show your special someone how much he means to you. It's imperative that you give your love a card with a romantic message written inside on Valentine's Day. It can sometimes be nerve-wracking trying to come up with the words to describe how much your special someone means to you, so put a lot of thought into your message. Get it just right.

Start your message by complimenting your Valentine. Say something romantic such as, "To the most beautiful girl I know," "you are are intelligent, beautiful, and funny" or "you always make me smile." Reading this message on a card from the man she loves will make her feel special and loved, which is what Valentine's Day is all about.

Begin your message to your Valentine with a romantic quote that reminds you of him. Use song lyrics, lines from a movie, or another meaningful quote that displays the way you feel about him. He'll be touched that you went through the effort to find such a meaningful quote that puts the way you feel about him into words.

Start your Valentine's Day message with a romantic poem. If you're a good writer, you can come up with a heartfelt message for her on your own. If you're not confident in your poem-writing abilities, you can also simply use another already-written poem that you find suitably representative of your relationship.

Valentine's Day is the perfect occasion to let him know how you feel about him, or to reassure him that your feelings for him haven't changed throughout the years. Sometimes the most meaningful messages are short, sweet and right to the point. Starting your card off with a simple "I love you" can be a great way to make him feel special and get your message off to a romantic start.
