40 Ideas to Help You Plan the Perfect 40th Birthday Celebration

There’s a vivid memory I always return to. When I was young, I remember my mom talking over the fence to a neighbor who was crying. When I asked why, she explained that the neighbor was turning 40. From then on, I assumed there would be something to cry about when I reached that age. Fast forward several years, and I couldn’t have been more wrong. I turned 40 last year, and there were no tears—only celebrations. After turning 40, everything has become clearer. My priorities, relationships, and who and what I spend my focus on.

For my 40th birthday, I wanted to share the things that light me up with my friends. I wanted to give them a peek into my practices and let them see the many layers that make me the woman I am today. So, I grabbed my girls and headed to Austin for an unforgettable trip. At 40, as a wife and mother, I’ve finally found the things that truly recharge my soul, so I wanted to give them a taste of that. The weekend included food for the soul, dancing the night away, a sound bath, vision boards, oracle readings, and a walk around Town Lake.
