It's important to do things fast: You learn more per unit time because you make contact with reality more frequently. Going fast makes you focus on what's important; there's no time for bullshit.

There’s a piece of advice I still struggle with, but that I’m more and more convinced lies at the heart of meaningful productivity, successful creative work, and a more vibrant life in general. That advice is: act fast. Move quickly. When you get a good idea, make it your default policy to put it into practice as soon as you reasonably can.
