Mental activity is the organism's dialogue with its environment.

So what I want to argue for is not that we should give up on our ideas of success, but we should make sure that they are our own. We should focus in on our ideas, and make sure that we own them; that we are truly the authors of our own ambitions. Because it's bad enough not getting what you want, but it's even worse to have an idea of what it is you want, and find out, at the end of the journey, that it isn't, in fact, what you wanted all along.

当你质疑别人都接受的假设时，真正的创新才会发生。
