Working quickly is more important than it seems (2015)
The obvious benefit to working quickly is that you'll finish more stuff per unit time. But there's more to it than that. If you work quickly, the cost of doing something new will seem lower in your mind. So you'll be inclined to do more.

"Nothing like this will be built again"
I've just had a really amazing experience: a guided tour of the nuclear reactor complex at Torness on the Scottish coast.
