"自宅ではいい人なんだけど、世界に知られたくないんだ。謙虚な人は、私が見てきた限りでは、あまり遠くへは行けない。"
— Muhammad Ali
Simplified Meaning:
The speaker is saying that while they're kind and nice in their personal life, they believe it's better not to let everyone know about it. They think that being too humble or modest doesn't help you succeed in the world. For example, imagine a person at work who always does good deeds quietly, like helping colleagues or going the extra mile on projects. If they don't speak up about their achievements, others might not notice their hard work and they might miss out on promotions or recognition. In essence, the speaker suggests that being modest can sometimes hold you back, and to get ahead, you have to show your strengths and let people know about your good qualities and accomplishments.
