Ask HN: How do you deal with competition

I have an idea. I know that millions do.

I'm willing to execute. That makes me a little different from the millions. I already started working on it, already spent some time and already see some results. That makes me quite different from the rest with the ideas.

But my problem is the competition.

There is competition, which is selling pretty much the same idea. I knew about it, but I always thought it's not good enough. It's not good enough for me and that's why I think I can make something better.

My question is if I this is enough. There's nothing that makes the idea unique. No extra feature, no additional value. Not in the idea. So should I refine the idea? Or maybe pick a different one? Or should focus on executing better?
