I have the exact same problem. Frustrated with how little progress I made in 2014, in January I sat down and thought about things I'd be happy to accomplish in a year. Which skills will make my 2015 a success? The two things I chose were non tech related: writing and meditation. These two tasks are my absolute priority this year since meditation will help with stress and anxiety, and writing will help with learning other new skills in the future.

With this in mind, it's easy to push away any new hobbies/subjects that would normally interfere.
