It is a good idea.
Line up work for that year and keep your mind active during it. Make sure you still read books or write, even just for pleasure, so that you don't regress back a few years.
Taking a year out can have two results:
1. You'll get the appetite to go back and learn and feel young again.
2. You'll feel as if it's time to stop the childish bullshit, earn a wage, and start your life for real.
Personally I'm between the two at the moment. It's always good to better yourself but you must also be practical.
