I recently read about a chap who set up a website last year which allowed parents to submit their childrens letters to Father Christmas and in return for a small payment, the child got a personalized letter through the post from the man himself. I forget the exact figures but this guy made something like $20,000 or $30,000 in the 12 weeks leading up to Christmas and I bet he is going to earn considerably more than that this year!
A simple idea and somewhat seasonal (to say the least!) but a very nice contribution towards his own Xmas expenditure nonetheless.
I did a quick search and found there are several sites now offering the exact same thing!
This will happen as soon as youre successful the moment you come up with a good idea itll be copied.
Anyway, Im not sure who came up with this great idea but you can take a look at the sites here, and whilst studying stay alive, spend every waking hour thinking of new ideas or asking yourself: how can I make that better or make someones life easier?
Be on an eternal quest for innovation.
