Your idea

At the start it’s just smoke, a wisp. It has no substance or form.

You can take it around to people for help shaping it, so you can better understand what it could be.

But the thing is, at the start it has no mass, and until it does it’s impossible for people to really do much of anything about it.  They can talk and you can talk, and that’s about it.

Mass gives it the ability to go places.  Mass means that with a push it can break through things.

Talk is fine, but the real work is giving your idea some mass.
