Let’s think about Twitter. In fact, the world is complex. To reflect that honestly, you usually need to focus on one thing for a significant amount of time, and you need space to speak at length. Very few things worth saying can be explained in 280 characters. If your response to an idea is immediate, unless you have built up years of expertise on the broader topic, it’s most likely going to be shallow and uninteresting. Whether people immediately agree with you is no marker of whether what you are saying is true or right — you have to think for yourself. Reality can only be understood sensibly by adopting the opposite messages to Twitter. The world is complex and requires steady focus to be understood; it needs to be thought about and comprehended slowly; and most important truths will be unpopular when they are first articulated.This took me years to realize.
