What an extremely tough thing to figure out: what to do with your future! Now, I can’t really tell you what to do, but I can share what I’ve learned looking back on my life. Here’s what I’d say. Even young people who have a plan (be a doctor, lawyer, research scientist, singer) don’t really know what will happen. If they have any certainty at all, they’re a bit deluded. Life doesn’t go according to plan, and while a few people might do exactly what they set out to do, you never know if you’re one of those. Other things come along to change you, to change your opportunities, to change the world. The jobs of working at Google, Amazon or Twitter, for example, didn’t exist when I was a teenager. Neither did the job of Zen Habits blogger.
