I love learning by doing.

Building MVPs and prototypes is the best way. Even better if you have a chance to show and share them in front of an audience (peer pressure can be good!).

Share the lessons you've learned and what you've done wrong, it will help many more people than just yourself.

I've been working for an eLearning company for the last 4 years (CloudAcademy.com) and I'm in love with the idea of learning something new every day. And not just coding. Code is "only" a tool to solve problems, and learning something about those problems and fields will make you a better developer.
