Every decade in our lives comes with a whole new host of challenges and changes. When you're in your 20s, it's all about navigating the world as a young adult. When you're in your 30s, you might be thinking about settling down and possibly even of having children. In your 40s, you start to notice changes in your health, and maybe you're evaluating and redefining your priorities. And then there's 50, which is a whole new chapter in your life, and a lot of the things that you've learned along the way are finally starting to sink in. Some of us dread turning the big 5-0. (That's why so many people associate it with having a midlife crisis.) But turning 50 isn't all about the march farther "over the hill" — it's so much more than that. Now that you're in your 50s, you've got more wisdom, more confidence, and you know what you really want. In other words, 50 is fabulous and should be celebrated accordingly. That's why we've pulled together a multitude of fabulous ideas to help you celebrate this important milestone. Here's all the inspiration you need to throw a fantastic 50th birthday party that's creative, personal, and maybe even a bit humorous. Whether you're planning a party for yourself, a sibling, or a friend, these themes and decorations are sure to please even the pickiest birthday gal or guy. And all of these ideas would work well for either a large party or even just a small gathering of close family or friends.
