Edit: I should also point out that the lines are intended to be aids, not indicators. If one starts focusing on the lines instead of on price, one may as well plot a bunch of moving averages. The lines are nothing more than a gauge of supply/demand imbalance. They do not provide support. They do not provide resistance. The behavior of price is always of primary importance. If the lines determine what you're doing, get rid of them.
For what its worth I have stopped drawing the lines and just visualize them in my head which actually in turn has helped me to stay focused on price. It has eliminated the "hope" that the line will hold. If price bounces hard and is about to break the line that would have been drawn that means something to me now then waiting and saying lets see if this line holds etc etc. I like it.
