innovation and real usefulness!

anything that you see that is succeeded is because they have had some usage in real world and that created demand for them.

for example when Apple created iPhones there was a lot of innovation in them. and there is usage for them too which creates the demand. people like having a small thing that has a ton of stuff in it they use (phone, camera, planner, internet, music, games, ....).

you can gather all the brains in the world and start a project but as long as that project doesn't provide anything that anybody wants it will be useless.
