Because you add a little bit more features.
Because you care a little bit more.
Because you make it a little bit better.
Because you lower the price a little bit more.
Because you put in a little bit more work.
It's tempting to believe that people will care just because you make it a little bit this or a little bit that.
And it's even more tempting to believe that people will care just because you do it.
But chances are they won't.
Chances are that if it's been done before it has to be exceptionally better.
And you'd have to care exceptionally more.
Make it exceptionally cheaper.
And put in an exceptional amount of work.
Or else people won't even care.
And they won't even bother switching...
"It'll be better if you do it."
If it's exceptionally better.
Which of course is pretty much impossible, or else it would already have been done before.
So what's the alternative?
To make it exceptionally different.
But not because it's going to work.
Because it probably won't.
But because it's probably your only chance...
