prov. be aware of your own strengths and limitations.

The Ancient Greek aphorism "know thyself" ( Greek: , transliterated: ; also with the ε contracted), is one of the Delphic maxims and was inscribed in the pronaos (forecourt) of the Temple of Apollo at Delphi according to the Greek periegetic (travelogue) writer Pausanias (10.24.1).

The maxim, or aphorism, "know thyself" has had a variety of meanings attributed to it in literature. The Suda, a 10th-century encyclopedia of Greek knowledge, says: "the proverb is applied to those whose boasts exceed what they are", and that "know thyself" is a warning to pay no attention to the opinion of the multitude.

In Latin the aphorism is generally given as nosce te ipsum or temet nosce.
