Downscale it. When I hit a point where I feel this is getting to much I radically downscale. Just create a section in your to-do for future upgrades where you move huge topics until only your core idea is left again. In reality things may turn out different anyway, so find the MVP in your idea and bring it to market. This is easier said than done, but reality is there is only so much one developer can do, and there is only so much motivation before you even bring it to market (feedback & cashflow help for motivation later)
