From this, I relized that I've been running the same calculation in my life all wrong. I've been developing reputation, good will, trust, expertise. All these intangible things that are supposed to protect you and create opportunities. And I still think they matter, but I'm starting to understand that they only matter as long as the other side values them. The second someone says your reputation isn't worth anything to them, it is worthless. You can be the most trusted person in your field, but your reputation goes down with it if the field ceases to exist or cease to be profitable.
I get your points. In some what journey of life someone who actually understand the reason we are created here is to live a life not just to how it will suit us but also considers it influence with the people around us.
Some had also believe life is garbage in and garbage out with the tunes of vanity upon vanity with the whispers of not suffocating others who had not made achievements up to your level.
Some would have the obligations to just fix human errors and instead of the people to be appreciative for such humanitarians, they would show their dubious and jealous life. So to an extent, some people are just ungrateful in life and does not deserve humanity favour with their selfish and evil minds full of envies.
So if you fall on the categories that portrays humanity, you should be careful because even those you feeds and teaches how to fish will somewhere want to bring you down.
A lot a just ingrate.
When ever our appreciation is not returned in good terms it is okay to feel disappointed but we cannot generalized human being that they are ungrateful or undeserving , human behaviour is very difficult and complex to understand. Our reputation or good will can never become insignificant just because one person or a group of people is not valuing them as we want, this idea that helping other is dangerous because some persons may not response positively is not good instead of focusing on jealousy and defection, it is important to understand that human interaction is the mixture of positive and negative experience.
A very generalized and realistic approach is to work with integrity and kindness and also set healthy boundaries rather than as you mean that people are inherently ungrateful or hostile.
