You're competing with everybody on this planet.
Every corporation on this planet.
Every blogger on this planet.
Every author on this planet.
Here's the thing:
You might not be in the same industry and you might not be competing to solve the same problem.
But what you and everybody else out there is competing for is your potential customer's, reader's or whoever's attention and money.
The attention of your potential customer is limited.
She only has a limited amount of attention every day. And her attention span decreases every single day. And at the same time the space filled with people trying to grab her attention is getting more and more crowded every single day.
If you're not able to stand out, to grab some of your prospect's attention they will never even realize that you exist.
So you might think you're only competing with companies that are in your industry. But in reality you're competing with almost every company in every industry out there.
The same holds true for your potential customer's (or reader's) budget. She only has a limited amount of money. And most of it is already allocated.
Even though you might solve a problem (or wrote a great book or blog post), that doesn't mean that your potential customer has any money left to buy it. Or that she has any attention left for today.
Her bandwidth is limited. Just like her budget is limited.
These days competition is not a horizontal thing anymore.
Competition has become vertical.
You're not only competing with companies (or writers or bloggers) from the same industry anymore.
You're competing with companies from every single industry out there..
