OP says after 4 hours of software development work, “they are done” and after that it’s just “obsessive tweaking”. They also say they started their own business and wanted to work part time at a company. Who is getting the “4 hours of work” and who is getting the “obsessive tweaking”? Not sure how these 2 statements align.
