Am6 did not work

[apollolux]

I tried to explain that you have to go through unhappiness to come back stronger

This idea is inherently wrong. The only legitimate result of unhappiness or "bad" things happening is you have a reference point for what is or isn't bad or good. A person doesn't automatically put themselves in bad situations or make bad things happen to themselves, either bad things happen to them or they're taught that they "did something wrong and the only atonement is punishment."

For a self-example, I only persevered through life because in the midst of all the bad things happening to me and people telling me I'm not good enough and sabotaging me someone said I was good enough and that I can have happiness and good things happen if I do the work. Perseverance was taught to me and it could have (and should have) very easily been done without all the negative stuff and it would have had a stronger effect because I would have only ever had a positive bias.

So no, you absolutely do NOT have to go through unhappiness to be stronger and be more appreciative of "the good things."
