"Not everything that is faced can be changed. But nothing can be changed until it is faced."
At some time we each have to face up to the fact that our mortal body will eventually die; nothing we can do about that. But we may not choose to face up to the fact that our relationship is in a mess, that we are in the wrong job, or that we have not been doing a good job bringing up our kids. In this state of denial, things just carry on the same, whereas if we faced up to the truth, it's likely a lot could be done to improve the situation.
