A really big error I've made around "discipline" w/r to software, is thinking that it means locking in all of your time so that you can crunch. It's the first two to four hours of effort, and the first 50% of your days in the month, that are important - when trying to chase after one thing all day every day, diminishing returns set in really quickly and you come out behind in terms of your whole life - unhappy and no better off on the project. Another hour or two on top can help when the job means you have to communicate with others. But even at a "normal" eight hours, you tend to end up with slack time, which is poisonous to how you treat the job. Discipline means starting consistently and stopping equally consistently. Starting without stopping isn't disciplined, it's desperate.
