Is there a place where Young Entrepreneurs can share ideas and connect with other Entrepreneurs?

I have some great ideas, I have a pion to be successful by being my own boss and creating ideas that will work for tomorrow's future. Is there any place to network and share ideas, knowledge, dreams for the young Entrepreurs of today? I'm 21 and ready to find more people adventerous and spontanous like me ready to make it big and love to do what they do for a living. Thanks everyone
