It is not that we have a short time to live, but that we waste a lot of it. Life is long enough, and a sufficiently generous amount has been given to use for the highest achievements if it were all well invested. But when it is wasted in heedless luxury and spent on no good activity, we are forced at last by death’s final constraint to realise that it has passed away before we knew it was passing.
Seneca, On the Shortness of Life. C 5BC – AD 65
