If you can't convince a small group of people today, you're probably not going to convince a large group of people tomorrow.
No matter how big your budget is or how many resources you have.
If it doesn't work on a small scale, it's probably not going to get any better on a bigger scale.
On the contrary, it's probably only going to get worse.
So don't waste your time trying to catch a whale, if you haven't really figured out how to catch a goldfish, yet...
