The thing about Eddison is that he didn’t discover electricity; he invented the first long-lasting incandescent lightbulb.
Columbus certainly didn’t discover America when so many had previously inhabited it.
The Wright Bros. didn’t invent physics but were able to create a vehicle that harnessed aeronautical engineering.
Inventing is to discover. And to discover is to invent.
The interesting thing is that when we discover something in ourselves, we also need to invent ourselves going forward. It also works the other way around.
