Time isn't a line; it's a dimension, like the dimensions of space.

People are curious. A few people are. They will be driven to find things out, even trivial things. They will put things together, knowing all along that they may be mistaken. You see them going around with notebooks, scraping the dirt off gravestones, reading microfilm, just in the hope of seeing this trickle in time, making a connection, rescuing one thing from the rubbish.

你必须愿意失败，愿意犯错，愿意带着学到的教训重新开始。
