Ask HN:I have a project in my mind. what should I do?

as you can see from my earlier topics, i have a food delivery app in my mind. i have been talking with people and i feel the idea got better. the tech people i talked with said me this sounds okay and feasible but i don't know anything about p2p systems. and i have been talking with a lot of tech people and i can't find a p2p guy. so im in a dead end. what should i do? should i apply to next yc batch? should i keep looking for a tech co-founder? should i try to learn it myself?
