True satisfaction is hard to come by, especially if we depend on and expect too much from others to satisfy our needs, because everyone is thinking the same way. We have to be realistic when we are living in such a chaotic environment, where everyone is trying to grab a piece of the same cake. If we have unrealistic expectations, then at the end of the day, we will only bring ourselves pain, and we cannot blame anyone else. After all, there is no magic bullet, and in my opinion, by knowing what is physically possible and achievable, we should pursue reasonable goals regardless of success or failure. With this attitude, we can at least move forward, rather than pinning our hopes on humanly impossible goals.
