Out of ideas: What to build/invent next age?

I'm looking for something like this.

Aren't we all...?
The question sounds vaguely familiar though...

How long does it take to invent something new?

The town where I live have less and access to electrics. They carry few arduinos, raspberry pi, three breadboards, few circuits, some parts sold out, etc. I got last sparkcore(sold out). I have few supplies to work with. I tried invent something new but I couldn’t make it work. Any ideas? How do I become successful inventors like Tesla, Edison, Steve Jobs, Musk, etc? I did work hard. How? I got the notes down.

Try to find something that annoys you every day. Then come up with a way to fix it
