The size of the opportunity you choose to go after has a significant role in the maximum success you may have, and that choice should not be discounted. Founders of billion-dollar companies such as PayPal and YouTube foresaw that the world was changing, and given many industries to choose from, they picked a couple of the largest possible markets where they could have an impact.
