The nature of setbacks can vary considerably. For example, a minor setback might result from a minor injury. Larger setbacks include the lack of knowledge that a certain procedural step or other condition is necessary for a project's success: If one attempts to keep working despite the lack of knowledge that this obstacle exists (let alone how to deal with it), one's lack of progress may prompt one to take long breaks from the project, to focus one's attention on other endeavors, or even to lose interest in the project altogether. Pirsig suggests preventing these kinds of gumption traps by being slow and meticulous, taking notes that might help later, and troubleshooting in advance ("e.g.", by laying out the requirements for one's project in logical and/or conceptual order and looking for procedural problems ranging from unaccounted-for prerequisites to gaps in one's instructions or plans).
