There can only be one 'first', and if yours isn't it than that's just too bad. The 'I thought of that first' meme is one of the most common and most easily dispatched things that almost all entrepreneurial types have experienced at least several times in their lives.

The easiest way to think of it is to realise that for every idea that 'made it' not just one but probably more likely several 10s and possibly 100s of people had that idea too and they didn't follow up on it either. Chances that you're the first are very small.

Your idea couldn't have gone anywhere, at least, not by itself. You need to get a lot more factors just right in order to create something that really takes off.

The more interesting question to me is what ideas do you have that you are not following through on right now, that you can make a similar post about 10 years from now?

And, what are you going to do about it?
