Never become a slave to a methodology; circles and arrows make poor masters. Pragmatic Programmers look at methodologies critically, then extract the best from each and meld them into a set of working practices that gets better each month. This is crucial. You should work constantly to refine and improve your processes. Never accept the rigid confines of a methodology as the limits of your world.
