Different paths, different personalities, different characters.

When the parents tell a child everytime he tries something that he got it wrong he is far more likely to give up in future.

In contrast when something goes wrong and a person sees it as a blip in a long line of mostly successes then he tries again expecting success the next time, or the next.

It's sort of like

0 0 0 0 0 0 0 0 0 0 0 0 ... person has had their fill of bad news

vs 1 1 0 1 0 1 1 0 1 1 ... person thinks it's worth trying again

I think maybe it's like physical pain. Everyone has a pain tolerance, some low, some high. We all experience pain, but not on the same level...I think there is an emotional pain scale like that as well. So while an event for some may be absolutely devastating, it's just a bump in the road for others. We all have a threshold, it just takes different amounts of pain to cross them.

Intestinal fortitude. When life hits a person in the face they either suck it up and do what it takes to push through, or they retreat to a safe space and try to get a law passed so they never have to confront that hardship again. When I see parents who drive their kids to the end of the driveway and sit with them in the car waiting for the school bus, I know that's a parent who's overprotective, and who will not let that kid experience any adversity. That leaves them completely unprepared for the hardship life is going to hit them with later when mommy and daddy ain't around.

People are biologically and psychology diverse. We tend only to consider edge cases when noticing it. Everything about everyone is somewhere on a spectrum for that particular feature. The combinations are endless and makes us truly unique. Your strengths may be the next persons weaknesses. Some people are lucky in their combinations, others not so much

Hard to say, some parents keep telling their kids everything they do is no good and it seems to get internalised and eventually they are reluctant to try anything. Other parents are encouraging and even if something doesn't work out the kids / now grown up, think next time they will succeed.

Total mystery

I think it's all a matter of perspective...there are too many variables to pinpoint exactly why this goes this way. But what do I know, I'm probably the most weak minded individual that I know.

Brain chemistry.

Elasticity, it's called elasticity.

Perspective.

Meh, it's a matter of perspective.

Some accept life's issues and ask "why me?".

Some see the same crap and ask "what did I do to earn this?".

I acknowledge this a very 1st world perspective.

I have earned every bit of trouble I've encountered.
Every bit of trouble I have ran into, is my own doing.
The second time
My problems are self wrought.

And I understand and accept that.

I've reached a point where acceptance of my own actions is my only way forward.

Just realizing your own role in things, it isn't easy.
I am at fault. Take it, learn from it, and hopefully fix it.

Because of chocolate. some people understand its' amazing powers. others eat kale and crap like that.

Everybody has things that will break them down. Some have more than others. Some are harder than others. But I think everybody has strength to resist, some just don't want to. There is an odd power in being weak. It can be a manipulation.

Because some have a Survivor chromosome larger than others.
