Disagree. I've literally run a startup where I took an opportunity I saw, pitched it to a cofounder, got a single client, cofounder did all the work. After year, cofounder was tried of doing work, so I told them how to turn the service into a product and rapidly got five clients; after that, the cofounder didn't have to do anymore work either.
I'm not lazy, happy to do hard work, but if I see an exploitable situation I will not create work just to feel good about things.
Do exactly what needs to be done, nothing less, nothing more.
Footnote: Not a fan of Edison, he in fact was lazy, refused to change, and spent a good deal of his life literally pounding rock to no end.
