It makes me happy when I see people around me fail.
What kind of failure do you like to see?
I like to see the kind of failure that makes my life better. Like when a coworker fails and I get a job opportunity.
You should better your self and not count on the failure of others. It is wrong to root for people to fail.
It's not like they'll ever know. It's just something that happens in my head.
Yes, but when you get excited over other people's failures, then you're less than a position to be able to support them. You'll make more friends if you can be a more compassionate and empathetic person.
