What does Rob Pincus mean by this? Very close to the time you learn a new skill, you should practice it as much as possible in order to fully ingrain that skill. However often you practice, whether it’s once a day, once a week or once a month, each practice session should be concentrated on the new skill you’ve just learned. Rob charts out how this should look over the course of eight sample practice sessions, with learning, practicing and evaluating three new skills.
