“One day the people that didn’t believe in you will tell everyone how they met you.”

Simplified Meaning:

Sometimes, people don't believe in you or think you can achieve your goals. They might doubt your abilities or not see your potential. However, when you prove them wrong and succeed, those same people often change their tune. Now, they talk about how they knew you, as if they were supportive all along. For instance, imagine you're an aspiring musician. In the beginning, your friends and family might not take your dreams seriously. They might even discourage you or say you'll never make it big. But after years of hard work, dedication, and successful performances, you become famous. Suddenly, the same doubters proudly tell others that they knew you when you were just starting out. This idea can be applied to anyone facing skepticism or doubt. Keep working hard and stay determined. Eventually, your success will speak for itself and those who once doubted you will have to acknowledge your achievements.
