Hard work pays off in time. Laziness pays off now.
However, laziness means that in 3 hours, you'll still have a bucket of work to do, and less time to do it, and less opportunity to enjoy anything which crops up in the meantime.
Leaving aside any argument about the future, it's probably better to just do it piece-by-piece and be able to relax. I normally break my law readings up with half an hour of painting, gaming or procrastination for every hour of work, and it's working okay for me.
