Don't over-conserve items that are used very frequently. Because these things are used repeatedly every day, the feelings they evoke—whether comfortable or uncomfortable—are directly and continuously perceivable. If an item is used very often but always provides a poor experience, we tend to comfort ourselves with, "I'll replace it with a better one when conditions improve." But over time, your subconscious will gradually develop a coping pattern of "making do and settling." Even if conditions do improve in the future, inertia may cause you to continue tolerating the discomfort. More importantly, each time we compromise on these unsuitable items, the dissatisfaction and discomfort generated during each use accumulate and quietly seep into other aspects of life, ultimately affecting our overall emotional state and quality of life.
