Jane struggled to maintain a daily meditation practice once the novelty wore off. She found it difficult to meditate for more than 30 seconds when she wasn't feeling it. The author argues that setting boundaries like committing to a fixed time each day, even if you aren't feeling it, can help build willpower and discipline. Not setting boundaries allows your inner critic to talk you out of sticking with positive habits. While it may feel uncomfortable at first, committing to boundaries is natural and will lead to improvement, unlike giving in to whims and moods.
