“Only an idiot would doubt my return.”

Simplified Meaning:

Imagine someone so convinced of their abilities and determination that they see it as foolish for anyone to think they won’t come back after a setback. This person is self-assured and confident in their resilience, just like someone who loses a job but is certain they'll find another or even better opportunity because they believe in their skills and persistence. It's like a famous athlete getting injured but everyone knows they will train hard and make a strong comeback. The core idea is about having unwavering confidence in oneself despite challenges. Applying this to your life means believing in your ability to overcome obstacles and not letting doubts, either from yourself or others, stop you from making a comeback. It’s about trusting that you have what it takes to succeed again, no matter the difficulties you face.
