Why do lesser people have such an effect on something as personal as your own self worth or composure? To put it another way, how can you declare someone and what they have to say as 'lesser' if they make you think or doubt?

Your question seems to have very little to with morality that isn't of your own consequence.

composure — TheDude

Rocks have incredible, Zeno-level, composure.

Is this healthy? — TheDude

Do you think being a rock/Zeno is healthy?

There are no correct answers to the questions I've posed above.

I will have to avoid lesser people from now on, so I don't get my inner peace rolled over again? — TheDude

One of the most difficult acts of the individual to achieve is the total abandonment of any type of morality - which are chains that make it impossible for the individual to be fully potentialized - however, if reached, the anguish of realizing that its ego is the only one truly freed is destructive for those not prepared.

You live with the anguish of wanting to get rid of morality, however, when you are able to break free, anguish makes you look down, where the sea of the ​​dull and contented mass resides, and while you look at it, it looks back at you , judging you, fearing you, envying you, all this and more because they are only they, and you are your own.

Ugh, no. There are clearly moral and immoral actions. Perhaps we don't understand which one's are which as journey onto old age, but that is where we test and ask other people.

OP, you have to learn how to handle other people. The clerk might think he's just having fun with you. Its unlikely he would want to drive a customer away after all. Have you tried playing along? Throwing some lines back in good humor? If he responds positively, you'll know it wasn't serious. If he responds negatively? He'll probably stop. Take it one step at a time.

Morality does not only apply to other people. It applies to you too. It is not about superiority and inferiority, it is about living your life to the fullest with minimal negative impact to those around you. If it bothers you, the worst thing you can do about it is nothing.

What makes a "moral" act be considered "moral"? I would say that a hegemony of thought - like a religion, a dogma, an ideology, a theory, etc ... -. We live in times where an absolute truth no longer exists because it has been completely discredited by the new generations, and now everyone is using its subjective truths - something internal; an internal knowledge perhaps? -. Neognosticism - commonly known as the lack of an absolute truth - is as present and real as the recreation of the classic globalized and secular world. The moral, and consequently, the immoral, no longer exist, because one depends on the other, and as the moral was "killed", the immoral is no longer obliged to exist.

Am I saying that this is good? No. What I argue for is that we should use that same subjectivity to create new concepts; concepts that make the individual and its egoism the center and focus of all human interaction and purpose.

In the case of OP, when you allow yourself to be freed from the putrid and common interactions of the masses, anguish - usually as a bad feeling, of strangeness, alienation - occurs, precisely by the act of freeing yourself from what is considered normal by the majority.

I don't get all this self-actualization and lesser-people talk. It sounds way too poetic to be real. Anyways if you're asking how to not care about what people think about you, there is no way to do it in a day. It's a process. Disclaimer: I am not a mental health specialist. Just saying what I found works. Usually the reason people care what others think is because they're scared of the consequences of what happens when they have a bad reputation or they have low self esteem (usually both). This is especially the case if you got bullied as a kid. The reason is that people with low self esteem try to get it from others' approval which never works in the long term. You have to learn to be unaffected even if the whole world thinks you're an idiot.

So what I do is:

1- Go back over conversations where you were offended and try to find alternate meanings to what was said. Maybe not everyone is trying to attack you all the time.
2- Learn to ignore people sometimes. I don't know if you do this too but I used to always take any insult or even joke as serious criticism. It's been getting better but I still do it.
3- Stop comparing yourself to others, whether or not they're doing better or worse.
4- Talk to people about it (friends family/ online chats for this thing)
5- Make more discussions on this forum. If you're on edge all the time then people arguing against your position will sound like an attack and users here don't mince their words so being in this environment will train you to not care about others' opinions as much.
