I remember reading Man’s Search for Meaning by the famous psychiatrist Viktor Frankl. During his time in a Nazi concentration camp, observing both himself and those around him, he wrote “I saw in myself and in others that the basic need for a human being is not pleasure, as Freud thought, or power, as Adler thought, but it is the need to have a reason to live and a reason to die.” And only faith can give these two reasons. Only a life in Christ can give us a reason to live, and can give us a reason to die. If we have both these reasons, our life will be full. And if our life is full, regardless of any difficulties we face, we will have joy. Metropolitan John of Korca
Other people may have other reasons to live, and that's ok for them. But you have to have something. If you don't have anything, there is no point. No reason for motivation to push you through from one day to the next. You'll be stagnant. You'll never change or grow. In my opinion, a life with out growth, is no life at all.
