"Oh, that's just a hack someone put together..."
Just about all the big decisions, innovations and perfect solutions around you didn't start that way.
They weren't the result of a ten-person committee, carefully considering all options, testing the reasonable ones and putting in place a top-down implementation that went flawlessly.
[The idea behind Amazon, the Mailchimp logo, the medical approach to childhood leukemia, the cell phone, the microwave oven, ethical email marketing, Johnny B. Goode, the Super Bowl, Kiva, Buffalo chicken wings...]
No, they were the result of one person, a person in a jam or a hurry or somewhat inspired. One person flipping a coin or tweaking a little bit more or saying, "this might not work" and then taking a leap.
Inventing isn't the hard part. The ideas that change the world are changing the world because someone cared enough to stick it out, to cajole and lead and evolve. But even though the inventing isn't the hard part, it scares us away.
Before you tell yourself you have no right to invent this or improve that, remind yourself that the person before you had no right either, but did it anyway.
