Ramit Sethi: “The 85 Percent Solution: Getting started is more important than becoming an expert. Too many of us get overwhelmed thinking we need to manage our money perfectly, which leads us to do nothing at all. That’s why the easiest way to manage your money is to take it one step at a time—and not worry about being perfect. I ’d rather act and get it 85 percent right than do nothing. Think about it: 85 percent of the way is far better than 0 percent. Once your money system is good enough—or 85 percent of the way there—you can get on with your life and go do the things you really want to do.”- page 8 of I Will Teach You To Be Rich.
While the quote above directly applies that money, I’m certain that’s true about many things (about 85% of them at least).
