Simplify your message. What is the core, key idea of what you want to do? If you can't explain it in a sentence, keep trying.

I want to "increase the number of people who are able to write, modify, combine and share software by building a tool that makes writing software easy and fun, and accessible to everyone." I even have a slogan. I call it "Enabling Software Literacy"

That said, I'm highly skeptical towards the "good ideas can be stated in a sentence" heuristic.

If you want anybody to listen, you're going to have to keep repeating it.

It's a good start. I can support software literacy. Now you need to state your plan to get there just as concisely. Probably not as easy.
