γηράσκω δʹ αἰεὶ πολλὰ διδασκóμενος
as I grow old I am always learning many things. (Solon fr. 18)

"As long as I was drinking by myself from the spring's water, it seemed sweet and good to me. But now it's become dirty and water is mixed with water. I'll drink from another spring rather than a river". (Theognis 959-962)
