Ideologically, we must realize that nothing is absolutely perfect; we must use actions, plans, and efforts to make things perfect, and achieve the relative best, not the absolute best; when things are not done, It is absolutely best, or when it is to the extent that you expect it to be, you must objectively analyze all the reasons. You cannot deny it completely or give up, deal with it rationally, and make a good analysis for subsequent plans or next implementation. But the above three points are based on the fact that you are a person with correct ideas, you have the ability to plan actions, and you can analyze problems objectively. In other words, if you can possess such qualities and abilities, you can turn perfectionism into optimalism.
