The income achieved by F10 drivers is not all that interesting to me. Interesting, however, would be the F10 drivers' occupations and the stories of hard work that got them to where they are today.
Some of the members on this forum show pictures of garages, cars, and other things that are beyond the reach of the income of mere mortals. Certainly some here have started and sold off businesses, etc. These are the stories that would be most interesting, perhaps because I currently own and operate a software business and am working towards my first big pay day (read: acquisition of the company).
The kind of success achieved by many of the forum's members usually only occurs through hard work and the use of a noggin. I enjoy reading about this.
