To draw a startup analogy, if you decide you want to take 25% of an established $100m market that's unlikely to happen because that's really hard to do, so people don't value your startup as having a potential $25m revenue. But if you can think of a realistic way to grow that $100m market to being a $125m market then people will readily accept you potentially have a $25m revenue business. Same result, very different impact.
Within your company you need to grow the market for your skills.
