What advice would you give your 18-year-old self and the youth in terms of startup entrepreneurship and dream fulfillment?

Hello everyone, I know it's not ideal to ask for advice and insights without being able to offer something back to the community, but I'm 18 and still have so little experience when it comes to being a start up entrepreneur or turning a great idea into a real business. It's my dream to create something that provides value to humanity and improves people's lives. I understand this path will likely be much harder than I imagine, and I'll need to make significant sacrifices to achieve this dream. That's why I'm working on making my why as strong and concrete as possible, so l can stay motivated and never give up, no matter how challenging it gets. Right now, I'm trying to gather as much knowledge as I can about topics like money, Al, communication, and business because I believe the more I learn, the better my chances are of finding a gap in the market where I can start building my business. That's why l'm reaching out to you: What else should I focus on? What do I need to learn? How can I keep my belief in myself strong? In five months, I'll finish school, and I need to think caref about the next steps I should take in mv Life What advice would you give me to help build a solid foundation for achieving my dream? What mistakes did you make along your journey, and what did you learn from them? I truly appreciate anyone who takes the time to reflect on their own experiences and help me by sharing their knowledge. Thank you from the bottom of my heart!
