Shoot for the moon. Even if you miss, you'll land among the stars." - Les Brown If you want to make a difference, don’t think about incremental. Think exponential. Think 10x. Think 100x. Nobody cares about the ones settling for 2x. If you can not shoot for the Moon, or Mars (since that’s a hot cake these days), why would anyone want to buy tickets to your ship? Folks today have private jets if they want to fly from Bombay to Boston. You think they will care about a better car ride from Street 1 to Street 2?
You've brought out the balance between dreaming and being pragmatic! :)
