"Innovate on existing platforms (We’ve got bicycles and mobile phones in
Africa, plus lots of metal to weld. Innovate using that stuff, rather
than bringing in completely new tech.)" really struck my mind, as a lot of times, we are trying to "improve" someone else life by introducing new technology that may not be relevant to the society. That's probably why certain companies can come out with innovative products like the Post-it note from 3M that is such a simple product, but took the world by storm.
