It's one of those rare stories that doesn't claim to take cutting edge technology to make it successful. Just people working together and owning a business, together deciding on their next move. And it has proven to work well. Wow, very inspiring.
I've never really believed in a recipe book for millionares. If the books like this really worked, every second person would be a millionare. I strongly believe that a millionare is the person who follows his/her own way and does it well, keeps on doing it when the whole world says: You suck, dude! You don't have to write or read a book about it. It's simpler -do whatever you want and if you do it right, you'll make it through.
