+###### “No great thing comes into being all at once, any more than a cluster of grapes or a fig. If you tell me, 'I want a fig,' I will answer that it needs time. Let it flower first, then put forth its fruit and then ripen. I say then, if the fig tree's fruit is not brought to perfection suddenly in a single hour, would you expect to gather the fruit of a person’s mind so soon and so easily? I tell you, you must not expect it.” —Epictetus, Discourses 1.15.7-8
