All ideas come from somewhere. All new ideas are just old ideas remixed into a new form. Sometimes when I’m remixing ideas, an attribute of one idea can amplify the impact of another concept. That’s how you know you’ve found a good idea.
I love dreaming up new ideas. I do it all the time; it’s probably my favorite hobby.
My strategy for brainstorming new ideas is to look at other ideas, bang them together, and see if something interesting happens. I tried to come up with an analogy for this, but the only visualization I could think of would be like a particle accelerator. In a particle accelerator, atoms get hurled at each other at high speed. Sometimes when the atoms collide, exciting things happen.
Ideas work the same way.
Smash a few ideas together at high speed, and you’ll start to pick up on patterns, and loose associations between distinctly different concepts. If you keep smashing ideas together, eventually, you’ll see a spark, and you know you’ve got something.
