I don't think it's always best to stick to it blindly. You start shifting your perspective from "I want to achieve my goal" to "I don't want to break the chain" and if you falter once you feel weak and worthless, and quit completely altogether. You just have to constantly remind yourself why you are doing this, know that repetition is the key and it's OK to miss some days here and there.
