What do you think of my career plan?

Ok, after my junior year of college I've been thinking about hopefully getting a summer internship somewhere like Cisco Systems or some type of technology company and hopefully landing a full-time job there after graduation...My plan is to work for at least 5 years in information technology then move out to Orlando or Miami and start my own company that provides technology solutions...my dream has always been to be a multi-millionaire(making over $30 Million a year), living an ultra-luxurious life, helping my family, and donating to charity....i know it sounds like a dream but is it realistic?
