At that time of day, when you feel so disgustingly bad, where do you wonder if it is really worth it? What good is it to strive if others do not? Why should you put all your effort, while others do not care? It is unfair, terribly unfair. Why strive, if in the end your effort will not be rewarded? Moreover, those who do not strive do not have any kind of problem or punishment.
Why not go with the flow and be the same as others? The more you fight, the harder you try, the more you try to have your own opinion, the worse it will go. Someone will always criticize you; always someone will be against what you say. Moreover, the worst, if you do things right and excel, no one will be on your side. Although there will always be someone to support you, they will always try to destroy you, there will always be someone who will want you to go wrong.
It is like a spider who catches a butterfly in its net, and the net, the more it fights, the more it becomes entangled.
