"It already exists" at first looks like a reason not to build something. But, is the version that already exists really the same as your implementation would be?

Outside of software, it's obvious that "it already exists" doesn't stop anyone. Does the long list of Italian restaurants, gastropubs or microbreweries stop anyone from starting another one, with their unique twist?

Even in software, did existing social networks stop Facebook from starting another one and taking over the top spot?

Does the existence of "a web application framework" stop anyone from building a better one that matches their opinions/approach?

The only real sin would be to make an exact copy of something that already exists without making your version better in some way. Make it more user-friendly, more powerful, more configurable, cheaper, more business-friendly, etc.

I had an idea around 2 weeks ago , thought about it worked on it, made the initial designs. Then just today i did a web search to see if there was something similar to it . What i found out was that it was already being done in some European countries for the past 12 years . Sure my app was going to be a little different but the basic idea was same , and if they had patented it , they would have sued me if my app ever got big. So it demotivated me and i trashed it .

Why did it demotivate you?
