Ask HN: What's your process of going from idea to live product?

For personal projects, it seems to me some people are really good at starting and finishing projects. Personally I'm fine if projects takes less than few hours, 2 days max. But I get overwhelmed, stressed and completely demotivated even just thinking about having to work on long projects. It looks like a never ending mountain, a mountain of suffering. All the 'big' projects I've ever done seems to have some things common - I'm beholden to someone else.. Monetary reward seems to be waaay less motivating. - Reward probability has to be 100%. Add any chance / risk & it's not worth it. Highly averse of looking stupid to myself for some weird reason. Personal projects often have no clear reward. Why work on futile things? - Deadline which would have resulted in certain loss. - Permanent! Achievement would also result in permanent gain. - Clear! I need a clear goal to hit, if it involves me figuring out what to do then that's the most amount of work. Again making a right decision is very crucial. I really wonder if there is psychological therapy that can change my brain calculus, any experience? But if I have a cursory idea and want to build it and see where it goes... brain is tsk forget it... then writing even one line of code feels like such a drag.
