Lick the stamp and send it.

The regret of never trying will (eventually) bring you greater sadness than a failed launch. The path of least pain is to launch. Do it.

I think you need to be able to answer that question. Spend some time going into depth understanding what really is holding you back. Only then you’d be able to solve it.

You're commenting on a post called "The Fear of Shipping", and you said above you're "afraid to ship". Now you claim you have no idea and could be anything, really.

There is nothing stopping you except your own bullshit. Do the minimum necessary to "ship" and if that's daunting, then you're trying too hard to be too big too fast and you'll never be able to get anywhere at all. Remember that if you actually care about a project, shipping isn't the end of it, but the beginning. You won't be happy with the results of shipping, because no one will notice and even fewer people will care. But if you ship it now, if the perfect user comes along, they'll find your URL somehow (maybe you give it to them) and fall in love with your idea without any further involvement from you. And then you can iterate.

If you don't ship now, then just accept your fate, and stop talking about these projects as though you're going to ship them.

Maybe fear of social judgement? What would you think of communicating first in a region with a group far away from your social circle ? EG if you’re asian and live in SV, silently deploy and ask people opinion in a related-field forum in the Netherlands or South Africa.

Bonus point: you expend your social circle.

Probably the worry over the next part, which you're probably subconsciously aware of. After shipping the product, comes the worst bit:

.....users......demands...monetary remuneration...support...maintenance...marketing...rejection...

Then it's not a fun educational experience anymore.
