I find it interesting to know what people aim for in a day or week. It's encouraging to know what people can accomplish in your own job as it means you could be earning the same if you try. If you have a target of £50 a day youll only earn £50. If you aim for £250 you may not earn it right away but if you keep trying, you could eventually get there! I have my own target for each day and it makes it easier aiming for it whether i do less or even more.
I do agree it's not a good idea broadcasting what you earn exactly on here though, especially if people know who you are and where your work is.... still a topic that I've often thought about and interests me though!
