Productivity isn't about writing lots of code. For example: if you spend 48 hours writing 10,000 lines of code, and then I produce same functionality in a normal 16 hours of work, with just 1,000 lines of code. Who is more productive? So instead of focusing on writing lots of code, focus on solving problems. The less code it takes to solve a problem, the better off you are, because that's less code to maintain. This attitude (explained in more detail here: https://codewithoutrules.com/2016/08/25/the-01x-programmer/ https://codewithoutrules.com/2016/08/25/the-01x-programmer/) then leads inevitably to the idea that working long hours isn't actually useful, nor is working at 2AM a good idea. The best way to be productive is to think, and that is easier when you are well rested, and works better if you take breaks and go do something else (https://codewithoutrules.com/2016/11/10/work-life-balance-software-engineer/ https://codewithoutrules.com/2016/11/10/work-life-balance-so...).
