My Second Year as a Solo Developer
I can closely relate to this post. Often times I build and develop software that is simply not worth my time. I think one important thing that you are doing well is capturing data for revenue. I think you should also take your hourly rate and multiply it by the amount of time it is taking you and that will give you a better idea of what this is costing you to build. I've started to capture this data for myself (https://marcell.me) to get a better idea of what it is actually costing me.
