The book is actually the idea that there are certain behaviors that you can engage in to make yourself more successful. The book teaches that as the pace of change increases, and information continues to explode, you need to embrace serendipity to succeed.
It’s pretty simple. First, you need to put yourself in a path for these unexpectedly good things. Second, you have to be able to see these serendipitous events — you have to make the connections. And third, you have to be able to act them. The definition of luck is that you were willing to do something.
