Learning on the train is a great way to increase my knowledge. I get half an hour that I can dedicate to learning. That’s not bad.
I’m learning UML now. I want to master it by the end of march. The book I have is great. It’s written in simple language with good explanations. Can’t beat that. But I don’t want to just read. I want to read, practice, and show. Reading in my case is not good enough. I need to practice. I need to take it into my long-term memory!
