These principles are useful when learning anything really: human language (immersion), programming (build something), sports (practice), etc.

That said, as someone who worked in software engineering for 5 years without a degree, and recently returned to school, I would say be careful not to discount studying theory at the same time you're practicing your craft. I really think a combined approach of structured university courses and MOOCs, including reading textbooks, along with applying the knowledge has been the best approach for me.

I was arrogant about "not needing" a degree for years, feeling justified by the fact that I was making very valuable contributions as an engineer, until I finally went back to school and realized how valuable theoretical knowledge can be.
