Whats your dream job!

I want to make new things for this world, things for the better. Technology, systems, software, items, vehicles etc. I would then like to become a multi-billionaire and start finding the cure to cancer and every other disease and open a private hospital supplying them because the government clearly wont tell anyone if they have a cure and cancer research aren't actually researching for cancer :/

I also wanna expand my twitch and youtube channel.
