No matter how you think best, whether in pictures or in words (in print or spoken), if your change is stuck behind an obstacle, find someone else passionate about your change and talk yourself through the obstacle.
Draw them the diagram or write out a few paragraphs and e-mail your writing to them, or have a nice conversation with them.
Don’t pull away from others as your change bogs down (which it will from time to time).
Instead, engage your other change believers and talk yourself through it in the way that works best for you.
You’ll be surprised how fast that big obstacle shrinks down to nothing when you work through it (or over it or around it) together.
Why not try?
