A lot of things happen for no reason whatsoever. They happen because they can. This fights with our desire to make sense of the world. If we can't understand the cause of things this time, how can we stop it from happening next time? If we can't discover the secret to success, how do we succeed? Accepting that some, perhaps most, things are just noise empowers us to focus on the stuff that matters. Wanting something doesn't make it so. Understanding what you can do, trying, failing, trying again is the only way to edge forward. That's a reason.
