Mindlessly hitting bucket after bucket at the driving range will not help take your game to the next level. Playing a mental game on the practice tee and going through your bag, simulating shots in the the same sequence they occur when out on the course can pay major dividends!
Picture a hole in your mind and visualize it on the range. Rather then just hitting your drive as far as possible, try to locate it at a target. Once you have executed this shot, picture your approach to the green, maybe you hit your drive 220 yards, leaving you with a 100 yard approach shot. Think about what club best suits you for this distance and once again pick a target you will aim at.
Practicing in this way helps to prevent you from simply developing a repeatable rhythm with once club as this is not a scenario that will often present itself when playing a round.
Finally, PICK A TARGET! Every shot hit on the range should be done with a purpose and final result in mind. One of the differences between amateur and professional golfers is that amateurs make the ball the target, while professionals make the flag the target.
