Why would you want to retire in 10 years? Isn't that like saying you hate your work? I enjoy my work, and am working to make it more enjoyable. The idea that I would try to live like a pauper so I could retire in 10 years and not do anything seems kind of strange.
If I retired, I would just find another job or career to make stuff.
Just because you have enough savings to retire doesn't mean you have to retire; it just means you have the option to. And "retire" doesn't mean you have to stop doing interesting work, either. You could keep working an existing job that you enjoy knowing that it's completely optional for you, or you could spend 100% of your time doing work that doesn't necessarily pay (e.g. a startup, or working on random Open Source projects that tickle your fancy).
