Leave your current company alone, and safe, and use a years worth of the profits to start something new. Keep doing that until second thing is making as much money as the first, then start changing your old company around. Best of both worlds, and you can still follow everyone's wonderful advice. Be safe man, don't goof up that absolute boon you are sitting in the middle of. Paramahamsa Hariharananda - "Shirk not opportunity, for opportunity may not come again."
