I have been thinking about three questions these days: One is why some people can make a lot of money without spending much time researching every day, while I work hard researching but don't earn much money. Where is the gap? Another is, why do I only see some projects after others release them? How did that person see them? Where is the gap? And the last one is, when the same information appears before me, why do some people feel that it is key information, while sometimes I overlook it? Where is the gap?
