A couple years ago I started pre-defining my years with a single word.
In 2014 my word was Transformational: I wanted to become a different, better person than I was. In 2015 I chose the to Compose my year: I was writing my first book and I was building the life I wanted. So far both terms have accurately described my last two years.
Because I stated how I wanted my upcoming years to be lived, I had a compass for decision making. For example, last year I faced the dilemma of continuing to work with the web design company I was freelancing with or focusing on my book full time. I chose the book. And in retrospect it was an easy choice, a non-decision, really.
