Morphology
The meaning is directly built from the constituents: 'know' (be aware of) + 'one's own' (possessive) + 'mind' (intentions/plans), so it literally means to be aware of one’s own intentions. This compositional pattern is common cross-linguistically and follows transparent possessive+noun semantics, so a B1 learner who knows the words can infer the meaning.
Etymology
Know one's own mind comes from the image of a person listening to their own inner voice so they clearly know what their mind wants when they must choose. So, it means 'to be sure about your beliefs or intentions and act on them'.
