My career was in sales. I had a great boss who said, "Percentages don't buy groceries, dollars do." This message is a gentle reminder that obsessing about one's savings rate percentage isn't really necessary. Watching the dollars will get you there, too. As a cancer survivor, I'd also suggest that it's important to maintain a balance between living for today and saving for the future. When you're old and long past FIRE, you're going to care a lot more about the quality of life you lived than what your savings rate was.
