What does the proverb it is always difficult to pose as something that one is not mean?

The proverb "it is always difficult to pose as something that one is not" suggests that pretending to be someone or something different from one's true self is challenging and often unsustainable. It implies that authenticity is important, as maintaining a facade can lead to stress, anxiety, and eventual exposure. Ultimately, it advocates for being genuine and true to oneself rather than succumbing to the pressures of imitation or deceit.
