The best way to come up with ideas worth doing

First, you’ve got to  enter into a creative state. So, start thinking about two businesses and/or concepts that when mixed up, they create a different one. For example:

Google + Tor Browser = DuckDuckGo

After you’ve done a bunch of them, start asking yourself:

What is always the same?

Then, do something different.
Airplanes used to have two wings on each side until Howard Hughes thought that it was stupid.
Roof tiles were boring until Tesla came up with the idea of using them as solar panels.
Now is your turn to come up with a remarkable idea. The one you’d be eager to put into practice. And actually doing it.
