What is the biggest misconception people have about life ?

That it is fair. Life is not fair.

That they have plenty of time. Time to learn, time to earn, time to save, time to do all those things they want to do.

None of us has enough time.

^^ Very true.. time is most crucial aspect of life which people very lightly.

Ha, ha. I was going to say exactly what @elbanditoroso said.
But that is tied with the following two.

I will add the second thing, is that free things don’t have some sort of obligation attach to them. So nothing is really free.

The third is that the world makes them miserable. Most people make their own misery and spoon feed their misery to others. Hence, they make up the miserable world around them.

That you can plan how it will work out.

That you can avoid the bad times. We all get them.

That you can be whatever you want.

You can’t.

You won’t get sick until you’re old.

I think our biggest misconception in the US is that the key lies outside us. We believe someone will bring us the answer. Instead, it lies within each of us.

That you are born with common sense.

That there are answers. Or a right choice.

Truly the absolute biggest is that life stops when this fleshly tent stops breathing, wait for it, you will see it here before the thread ends.

that people are inherently good.

That you’re in control.

I believe very strongly in the goodness of people.

learned goodness, maybe.

Well, “good” is subjective, so it is always learned to a degree. But, as social animals, most of us have similar goals and hopes and dreams, and while we often disagree on how to obtain those things, it’s generally out of shortsightedness and not badness.

I don’t think people are bad. I just don’t believe in innate goodness.

That it has a purpose.

^^ I don’t think people are bad. I just don’t believe in innate goodness.
Where does that have people starting off as, brain dead meat carcasses in need of programing?

Yes, obviously.

That there is an afterlife.

You can never know everything.

To believe that a God will provide salvation.
