I have been working through the Big Nerd Guide for Android Development. The book is not API 21 and Android Studio ready. It focuses heavily on backward compatibility. This has become a little problematic for me. But in any case I have decided to cruise through the book and finish it for sake of aesthetics. For sake of finishing it.
In order to improve my focus I have been using Pomodoro technique. After working for 4 pomodoros’ I lost my focus. 2 hours of focused work is better that sitting whole day and pretending to get work done.
Working with full devotion is something that one must cultivate over time.
