Carefree SAE

When I was 19 I travelled the world for 9 months before starting university. It was an amazing experience and the love of travel, adventure and exploration has never left. I particularly loved the time I spent on a tiny Pacific Island. I was young and carefree with very few responsibilities. Fast forward 30 years and I am married with two young children all of whom I love dearly but I still find myself yearning for those happy, carefree days spent on that tropical island enjoying life alone. How can I harness those feelings of happy, carefree days in my current reality which feels very different since I now how many responsibilities and cannot just jet off on my own to the island paradise of my youth? Instead my feelings are more a lack of freedom and the weight of responsibility which in turn make me feel trapped and somewhat sad I guess. Maybe some regret of choices made? Thank you
