When it comes to writing a 40th birthday card, it can be tough to know just what to say. Here are some ideas to help you get started:

• Wishing them a happy birthday: Start with a simple message wishing them a happy 40th birthday. For example, "Wishing you a very happy 40th birthday. May all your dreams come true".

• Complimenting them: Let them know how amazing they are and how much you appreciate them. For example, "Happy 40th birthday to one of the kindest, most thoughtful, and most amazing people I know. Have a fantastic day".

• Joking around: If they have a good sense of humor, consider adding a funny message to the card. For example, "Happy 40th birthday! Youre not getting older, youre just getting better".

• Reflecting on their life: Take a moment to reflect on their life and accomplishments. For example, "40 years of wisdom, laughter, and memories. Heres to many more".

• Encouraging them: Encourage them to embrace their forties and all the joy it will bring. For example, "Get out of your comfort zone to fulfill a dream youve always had".

• Making them feel special: Make them feel extra special by expressing how much you appreciate having them in your life. For example, "Through a 40th birthday wish like this, you not only want to share your excitement to celebrate them, but you also want to express how much you appreciate having someone so wonderful in your life".

• Using a quote: Consider using a quote to add some inspiration to the card. For example, "As soon as you feel too old to do a thing, do it".

Remember, what you write in the card will depend on your relationship with the person. Whether you make them laugh, feel empowered, or help them forget how old they are turning, the most important thing is to make them feel special and loved on their special day.
