1) Who are you building for? Customers (paying ones) are everything [in startup land].
2) Sounds like you need both supportive morale-boosters (rare) and a cool co-founder (even more rare).
3) Go to some in-person meetups for startups or even ETH conferences (I have no idea what you are working on but you need supportive people around you)
4) Consider joining a large company where you can work as an engineer of some sort and use it as a place to meet/network with potential future co-founders. You can meet sharp-and-cool people this way.
5) Focus on one project.
6) Don't sell the product, sell the dream. People don't buy products, people buy what the product enables them to do. (Mario doesn't buy the fire-flower, he buys the ability to shoot fireballs - as I heard in a video once)
7) Read all the biographies/autobiographies/essays of people who are successful in startuplandia to glean insights into what to do next. Your acquaintances who have never embarked on this journey before will be of limited help, not due to lack of want , but due to lack of expertise/experience.
8) People owe you nothing; until you provide/give them a service or an experience people will not feel the need to reciprocate, and even then reciprocity is increasingly rare in 2027 / the kaliyuga.
