Could less discipline improve productivity?

This is a great discussion about the realities of practical time and task management. So much of the "guru's" tips techniques and tools are inflexible and lack proportion that they become unwieldy and actually get in the way of real productivity. This thread addresses that reality and provides suggestions for using your time management tools and techniques in a disciplined but flexible manner that benefits but doesn't enslave.

It's like having a realistic and healthy diet that isn't so restricted that it's impossible to adhere to. A little wiggle room prevents the inevitable failure that can often occur when realities of cheesecake and hot dogs are confronted in the real world.
