Setting goals is common in our life. We look ahead, predict what may make us happy in the future, and then narrow down the things to something specific. For the most part, having goals is better than not having any, but there are also problems that come with spending an entire life living from goal to goal.
For one thing, we try to predict an unpredictable future. Who is to say that what you want next year is the same thing you want right now? What if what you want right now isn't in the right direction over the long term?
Secondly, and just as importantly, you only confine your expectations of happiness and satisfaction to the goal you have set so that you often forget that other things in your life can also add just as much joy to your experience. This creates a strange problem.
To solve this problem, we have to move towards something more unclear. Going after interestingness. I think, is what we should do.
Interestingness doesn't mean looking for pleasure only. It's deeper than that. It's doing that random (随机的) project you had no plan to do because you have a feeling that you might just learn something you didn't know about yourself. It's seeing a person you just met not as a possible partner or someone who can do something for you but simply as someone who may open a new, unknown and unique world for you.
Goals incorrectly assume (假设) that we already know what we want. Interestingness is more modest. It makes up its mind as it moves, slowly blowing from one thing to another, until it catches something that lies beyond prediction at last.
