Everyone wants to change the world, but no one wants to change himself. This is because changing the world needs more external support, and this ideal will become fuller. Because everyone has a desire, it is a challenge to change themselves, so it is not easy for most of us to change ourselves. Since it is not easy to do, it is natural to do it. So, just can have such an idea. Everything will be brilliant on your own, and you won't complain about the immediate suffering. This is just paving the way for you. As long as you are willing to change and work hard, your life will definitely improve. Do not hesitate. As long as we persist in working in one direction, quantitative change will reach qualitative change sooner or later.
