Life-changing lifestyle shifts: What's your story of transformation?

For years, I was a night owl who struggled with mornings and felt constantly exhausted. On a whim, I decided to try becoming an early riser. The first few weeks were brutal - I felt like a zombie and nearly gave up multiple times. But I stuck with it, gradually adjusting my sleep schedule and creating a morning routine I enjoyed. Six months later, I'm amazed at the difference. It wasn't easy, but the impact on my overall well-being has been profound. What significant lifestyle change have you made that had a profound impact on your well-being? How did you maintain motivation during the transition?
