If you feel that strongly about it, then that just shows your passion and commitment—and that’s incredibly admirable. The beauty of chasing something so ambitious, like a Fields Medal, is that the journey itself is meaningful. Whether or not you "get there," you'll have explored ideas, pushed your limits, and lived fully immersed in something you love.
But don't forget to take care of yourself along the way! Even the most brilliant minds need rest, laughter (which you clearly have plenty of!), and moments to enjoy life outside the pursuit. You're not just chasing a medal; you're crafting a story that’s uniquely yours—and that’s what truly matters.
