It's important to have principles and boundaries; some things shouldn't be constantly yielded, otherwise, more and more trouble will arise.
Learn to say 'no' to unreasonable requests from others.
In life, many people are troubled because they are embarrassed to refuse, often living with distress. Sometimes, they are afraid of hurting others and force themselves to do things they don't like, gradually realizing that not being able to refuse has become a habit, and they are always afraid of ruining others' plans, so they dare not decisively say 'no'!
It doesn't need to be regrettable, refusing is your right as a person.

Kindness is not about accepting everything, sometimes you need to take care of your own emotions and say 'no' in time, which is to stop others from harming yourself and liberate yourself.
People must learn to say 'no', decisively reject things they don't want to do, don't hesitate, don't be vague, the attitude doesn't have to be harsh, but it must be refused.
In this way, you're good, and others are good, you must clearly express the refusal, free yourself, and also prevent others from fantasizing.
When faced with conflict, don't shrink back blindly.
People should have bottom lines; some things don't need to be constantly yielded, otherwise, more and more troubles will arise. You always have to swallow your anger.
Many times, we think stepping back can create vast skies, so when facing conflicts, we silently shrink back and avoid, either don't speak, or endure criticism silently, or constantly apologize, hoping to resolve the conflict by appearing weak, but often the opposite happens. There are some people in this world who are opportunistic and take advantage of others' kindness, and if you're kind, they'll take advantage of it. If you're not kind, they'll use it against you.
Some people, some things, we always give them a little leeway, but unfortunately, they not only don't understand, but also turn around and accuse you. When you've reached your limit, you should stop tolerating it.
Kind people are often more approachable and easier to be accepted and recognized by others, but in another situation, excessive kindness without resistance can lead you into a bottomless quagmire.

When faced with unkind people's unreasonable demands, the best way is to refuse from the beginning, even if they're unhappy, it lets them know your temper.
A kind person should also have their own aura. Only when you have the confidence not to be arbitrarily controlled by others, you don't need to give unscrupulous people a chance.
It's also a kind of cultivation to not give evil people leeway.
