I'm rather low on time today, so I shall leave you with some words of wisdom by Theognis of Megara (Θέογνις ὁ Μεγαρεύς, Théognis ho Megareús). He was a Hellenic lyric poet active in approximately the sixth century BC. The work attributed to him consists of gnomic poetry quite typical of the time, featuring ethical maxims and practical advice about life. He was the first Hellenic poet known to express concern over the eventual fate and survival of his own work and, along with Homer, Hesiod and the authors of the Homeric Hymns, he is among the earliest poets whose work has been preserved in a continuous manuscript tradition (the work of other archaic poets is preserved as scattered fragments). In fact more than half of the extant elegiac poetry of Hellas before the Alexandrian period is included in the approximately 1,400 lines of verse attributed to him (though several poems traditionally attributed to him were composed by others, e.g. Solon, Euenos).

"If someone praises you for as long as you see him
But lashes you with an evil tongue when you are apart,
That kind of man is not a very good friend at all.
He’s the kind who speaks smoothly with his tongue, but harbors different thoughts.
Let me have that kind of friend who knows his companion
And puts up with him when he’s mean or in a rage,
Like a brother. But you, friend, keep these things your heart
And you will remember me in future days."
