I am focusing more on building things with tools I have never used before. Constantly retrospecting my choices in professional and personal life to find ways to do things better. Also the usual - reading books, blogs, following better and smarter people on Twitter. I avoid LinkedIn... it's just an echo chamber on high-fives now.
Challenging myself. Reading books that are hard and maybe not relevant to my current job but super interesting and provoke ideas. Most recent example is <i>The Master and His Emissary: The Divided Brain and the Making of the Western World</i> by Iain McGilchrist.
Reading, experiencing life, balance between mental and physical activities, creative self-expression, trying to view the world from a perspective other than my own.
