6. You do deliberate practice to improve your ability to perform a task. It’s about skill and technique. Deliberate practice means repetition. It means performing the task with the aim of increasing your mastery of one or more aspects of the task. -- Jon Jagger Monday, March 12, 12
7. In software we do our practicing on the job, and that’s why we make mistakes on the job. We need to find ways of splitting the practice from the profession. We need practice sessions. -- Dave Thomas Monday, March 12, 12
