The document discusses the importance of practice for developing skills as a musician or coder. It quotes Jascha Heifetz saying that lack of practice for one day is noticeable to oneself, two days to critics, and three days to the public. For both music and coding, regular practice is needed to develop craftsmanship and mastery, as over half the time on projects is spent thinking rather than actual coding work. Cloud-based development environments can give developers an extra 48% of time to spend on design and coding through improved tools and workflows.
