Big fish in a little pond
There's no doubt that the big fish gets respect, more attention and more than its fair share of business as a result.
The hard part of being a big fish in a little pond isn't about being the right fish. It's about finding the right pond.
Too often, we're attracted to a marketplace (a pond) that's huge and enticing, but being a big fish there is just too difficult to pull off with the resources at hand.
It makes more sense to get better at finding the right pond, at setting aside our hubris and confidence and instead settling for a pond where we can do great work, make a difference, and yes, be a big fish.
When in doubt, then, don't worry so much about the size of the fish. Focus instead on the size of your pond.
