Pretty much -- i've been too tied up in Product Development lately, and seeing how those principles tie into other things around us (like the environment). My company has been working towards more environmentally friendly products (recycled and biodegradable packaging, better production methods, etc.), however there is still a ways to go.

Just because something isn't perfect, it doesn't mean you give up. It means that you work harder to make it better, constant improvement. And the environment is the same on a much broader scale. Like, using Lady's Human light example ---

1. Right now? Incandescent bulbs.
2. The Improvement? Compact Flourescent, which still have problems for recycling, etc.
3. The Improvement? Lady's Human light example of LED and LED Film lighting (Light Emitting Diodes, look at the little green light on your PC tower, thats an LED) ... better.
4. The Improvement? ...

And so on -- There may not be perfection, but theres always 'Better' and 'Improving'
