We tend to avoid making too many decisions as it requires mental energy. The only thing we have in life is time and mental energy, hence we have an inherent aversion of spending it on things that require a lot of them.
Changing your mind or making decisions take up mental energy you’d like to preserve, which is why they are hard.
Many of us eat the same meals most of the time, wear similar outfits, and follow routines. This tendency usually serves us well. But the status quo is not necessarily the optimum solution. Indeed, it may be outright harmful or at least unhelpful if something has changed in the environment or we want to optimize our use of time.
Inertia is a pervasive, problematic force. It’s the pull that keeps us clinging to old ways and prevents us from trying new things. But as we have seen, it is also a necessary one. Without it, the universe would collapse. Inertia is what enables us to maintain patterns of functioning, maintain relationships, and get through the day without questioning everything. We can overcome inertia by recognizing its influence and taking the necessary steps to create that all-important initial momentum.
