Do you know the pros and cons of coffee?

Life is like a cup of coffee, maybe it is bitter and no one wants to drink it, but whether you want to or not, you will drink it in one breath.

Some people will cherish it and slowly taste its bitterness and sweetness; some people will not cherish it and drink it without any temperature, without noticing anything. But most people do not choose either of the two, seeming to feel that this is a painful way, and want a third way to solve the problem; they are silent in the darkness and do not want to see the dawn of hope.
