My Own Lawyer

The phrase, "soy mi propio abogado y me temo que voy perdiendo" (which translates to "I am my own lawyer and I fear I am losing"), is not immediately identifiable as a single, famous quote from a specific well-known person or literary work in Spanish.

 * It is a widespread, common-sense expression that many people use to humorously or ruefully describe a situation where they are arguing a difficult case for themselves (often in their own mind or in a personal conflict) and feel they are failing.

 * The concept of being your own lawyer and losing is a very relatable and often-cited idea or witticism, but the exact phrasing you provided doesn't link back to a single, famous source like a novelist, philosopher, or historical figure.

It is likely an idiomatic saying that has become popular due to its universal relatability, rather than a direct, attributable quote.

Is there anything else I can help you find about this expression or similar phrases?
