DISCUSSION ~ How do you decide on YEARLY READING GOALS?

We all know the drill by now, since it's something that's so "general" and.. world-wide known: setting yearly goals whenever the start of a new year is approaching. Those goals can include anything at all, but.. for us specifically? There's always some kind of reading goal involved. Reading goals that remain goals for a while, but eventually turn into a challenge because.. we always, always need to catch up on them. Then, after a while, the pressure comes into the mix because we really want to succeed and be able to say "I did it!" at the end of the year. But is it really all that realistic to put up a yearly goal without knowing what's going to happen throughout the year?
