Letters 25.7
You ought to make yourself of a different stamp from the multitude. Therefore, while it is not yet safe to withdraw into solitude, seek out certain individuals; for everyone is better off in the company of somebody or other,—no matter who,—than in his own company alone. “The time when you should most of all withdraw into yourself is when you are forced to be in a crowd.” Yes, provided that you are a good, tranquil, and self-restrained man; otherwise, you had better withdraw into a crowd in order to get away from your self. Alone, you are too close to a rascal. Farewell.
Seneca, Letters to Lucilius 25.7, translated by Richard Mott Gummere
