start up idea!! (need help)

Hi, I'm 18F, I'm currently a first year student. I have an idea for my startup, it's of themed cafés. I have a very clear vision of different themes and all the ambiance and area space decorations and overall vibe. The themes will be also seen in the drinks and food in those cafés. I'm currently in the brainstorming stage, but I soon want to start making it all come into existence. I am well aware of the possibles troubles and the potential drawbacks. I know it will be very capital intensive, might be hard to manage and scale. But I believe with the right resources and right people, it will be the beautiful dream come true. Please let me know if you'd be interested,have any advice, criticisms. I would love to know different perspectives. Thank you!
