Sure. I would offer two ideas which may resonate or not. They aren't provable facts, but experiences from my life and others'.
1. Part of your desire to sail the world is having it as a dream. It's the scarcity of being able to sail that gives it such high value. When you remove that scarcity with complete time and money freedom (and after some time, normalize yourself to it), the reality of sailing the world might change your perspective.
Now you have to acquire a boat, gain a shitload of knowledge, care for and repair it, invest significant effort to plan and prepare a trip, take significant risk being out on the ocean, be alone for months or recruit people to come with you, can you be alone with just them for months, is the opportunity cost of being away from family and friends for so long worth it... etc. It's no small feat.
Depending on how you are wired, your body might MUCH prefer to sit at home, eat tasty food, and submit to the youtube algorithm. Now that you have time and money freedom, you don't HAVE to do anything! I think your body knows it, and will optimize for risk reduction and energy conservation.
caveat: if there's something more here, like your late father taught you how to sail and you grew up on a boat, or your best friends are entering an international organized race, then for sure you will likely sail.
2. What happens after you sail the world? Do you sail it twice? Maybe you find it enough to just be at sea forever, but likely you come home to your apartment/house and .. do what exactly? The next thing on your list after "sail the world" perhaps, and repeat. If my first point doesn't terminate the loop for you, you can chase your next desire and next desire. Is that a life well lived?
Lots of people absolutely retire and live happy lives. But my sense is that they are much older, and so are still motivated by time scarcity, just in the fatal sense. Or they invest themselves deeply into something meaningful outside themselves like community, charity, teaching, caregiving.. or WORK! Then you'd be back to where you are, with some new experiences under your belt. Totally worth it. But I'd guess that almost no one puts their feet up and happily sips a mohito on the beach for 50 years.
