We keep moving forward - opening up new doors and doing new things - because we're curious.

Democracy... while it lasts is more bloody than either aristocracy or monarchy. Remember, democracy never lasts long. It soon wastes, exhausts, and murders itself. There is never a democracy that did not commit suicide.

The most important political development of the last two centuries has been the rise of the modern state.

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.

"We are all just passing through, leaving traces of ourselves behind like footprints in the snow."
