Currently reading Children of Men. This bit right at the beginning hit home. I try to get in the mindset when I get depressed of just being present in the moment and accepting that all there really is in reality is the present moment. It helps to try and distract from worrying about the future or having anxiety about the past

Pleasure need not be less keen because there will be centuries of springs to come, their blossom unseen by human eyes, the walls will crumble, the trees die and rot, the gardens re- vert to weeds and grass, because all beauty will outlive the human intelligence which records, enjoys and celebrates it. I tell myself this, but do I believe it when the pleasure now comes so rarely and, when it does, is so indistinguishable from pain? I can understand how the aristo- crats and great landowners with no hope of posterity leave their estates untended. We can experience nothing but the present moment, live in no other second of time, and to under- stand this is as close as we can get to eternal life. But our minds reach back through centur- ies for the reassurance of our ancestry and, without the hope of posterity, for our race if not for ourselves, without the assurance that we beipg dead yet live, all pleasures of the mind and senses sometimes seem to me no more than pathetic and crumbling defences shored up against our ruins.
