Never, ever be separated from your hobby for so long that, when you sit at your desk and view the terrain, you have no idea where to start. -_-
This is why practicing the discipline to do your craft daily is important. Even if you set a time goal rather than a production goal, any completed task is epic… to say nothing about how it makes the daily goal a little easier to attain each day you are successful.
Needless to say, this is my goal at the moment: to sit down at my desk each day and produce something, even if it is simply a matter of getting the area a bit more manageable.
