Expand your thinking about computing and programming by learning where it all came from (and opportunities we’ve missed). Fantastic talk by Bret Victor, and love this bit at the end:
The most dangerous thought you can have as a creative person is to think that you know what you’re doing. Because once you think you know what you’re doing, you stop looking around for other ways of doing things. And you stop being able to see other ways of doing things.
To really understand why he says that, you’ll have to watch the talk.
