[If] people who travel… tire themselves out on the very first day by rushing along, they will end up wasting many days as a result of sickness. But if they start out walking at a gentle pace until they have got accustomed to walking, in the end they will not get tired, even though they walk great distances. Likewise anyone who wishes to embark on the labors of the virtuous life should train himself gently, until he gradually reaches the full extent of his abilities. Do not be perplexed by the many paths walked by our fathers of old, each different from the other. Do not overzealously try to imitate them all-this this would only upset your way of life. Rather, choose a way of life that suits your feeble state; travel on that, and you will live, for your Lord is merciful and he will receive you, not because of your achievements, but because of your intention.
–Evagrius Ponticus (345-399)
