Actually, you might be relieved to know there is no failing here! Rather, each slip is feedback to help you learn what works best for you.
This program is built around experimenting, because life flows in seasons, and transitions are not a matter of 'if' but 'when' - so building a mindset around noticing, making adjustments, and adapting with change is all part of the resilience we're building.
Remember, RESILIENCE is the goal, not perfection.
