Where do you look for your next big opportunity? Many people tend to follow the masses and what they are doing. That's why they call these people the masses - there are a lot of them.
The challenge is, by the time the masses hear about and begin taking action in an area, most of the tremendous opportunity is already gone. People are competing on price which means profits are being squeezed.
Think about the explosive growth companies - Apple, Microsoft, Google, Uber, Facebook. These companies were in at the beginning of their industries with little to no competition... and often without even an industry in place yet. They created entire industries based on their success.
The largest opportunities for huge success come from exploring areas no one else is in. This is exactly what the founders of the companies listed above did. Doing the same allows for the explosive growth most entrepreneurs dream about. As a bonus, even when competitors come in, they still must tackle the giant to be successful. It creates a competitive advantage for you.
Look for ideas which address a human need or desire in a new way which no one else is doing. Then look for a method to deliver the solution to this need. This will provide you the opportunity to be the next big thing in our world.
