"A menudo en el mundo real no son los inteligentes quienes progresan sino los valientes."

Simplified Meaning:

People who take risks and put themselves out there are often the ones who succeed, rather than just the people with high intelligence. For example, think about a classroom setting: a student might be very smart and know all the answers but they're too shy to speak up. Another student might not be as smart, but they're confident and always willing to try new things and speak their mind. This second student often gets noticed more, gets more opportunities, and might even end up doing better in the long run because of their boldness. Being brave and taking action, even if you're afraid, can lead to success more often than just being very smart but not taking any chances. So, it's important to have courage and make bold moves, because that's often what gets people ahead in life.
