The problem i see is that people limit them selves saying "to do X first i need W and i don't have W".
You need to start with anything, NOW. No excuses. NOW... then you will find a bunch of new "problems" to solve.
You are in a "blind spot" until the ball starts rolling.
So I've got a problem and an outline solution. I just need R&D capital and a few months in a workshop to create a prototype, get a patent and then take that looking for investments ...
How do I start "NOW" with what I have, no money, no time, no workshop.
Enthusiasm doesn't solve every problem.
You can save money and sure you can invest less time on hackernews and more in your ptoject.
If you can't do anything of that for what you have in mind try to go for something smaller but always thinking in the long-pitch.
I'm just saying ..
Time I can probably manage a little of, but then I use HN for relaxation when I'm tired so it's not really productive time that I'm using up. The project is nothing without capital and a workshop; just dead.
Sure there's other things to do but then I'm giving up on the project and that would be falling to the point you attacked that to do X [this project] I need Y and Z.
