People donate 80% and get 80% of their returns. But what if you give you a 300% refund? I believe the real breakthrough happened in the past 20%, and almost no one was pushing wildly. The extra 20% requires obsession, delusion, and even some wounds that may make you quit. When you move forward for a long time after Logic says it stops, it's OK. Because in the end, success has nothing to do with talent or luck. About who can tolerate the longest time. Pain is a test. Most people fail before they are about to succeed.
