Don't think so, you know, everyone is either born to take advantage of others, or is taken advantage of by others first, and then slowly learns to be cunning. It's just nobody told you. Now this society, as if it won't take advantage, has been characterized as derogatory, so everyone learns not to let themselves suffer. So you should learn slowly. Remember, every time you suffer, ask yourself why you suffer, whether that sentence is wrong or that thing is wrong. In short, you should learn a lesson and don't do it again.

In addition, I personally think that the loss mainly depends on who you give the loss to. If you are a treacherous and cunning person, you must live up to your expectations and not let him always take advantage of you and fight back. If you are some real or close friends, it is a blessing to lose yourself, but you must eat clearly so that those who take advantage of you can clearly realize it.

Also, although you must have some means in society, please don't forget your positive beliefs, and remember that we have to do it because we have to. If conditions permit, we will be the kindest people.
