That's funny it only took me 4 years and twice around the world to get to a reasonable income. That was full time with one day a week at London Collage of Printing (and graphic arts as it was then). Gave up full time when computers became more lucrative, instantly doubled my income!

Nikon have change over the last few years, looks like the accountants now have control. They could go the way of Eastman Kodak if they are in control.
Modern (and old) businesses have to plan ahead and not just 4 years like a government but long term. As soon as you cut research you cut you future!
