Controversial to me: "if you can overlook an error in another person, should you overlook the same error in yourself?"?

Depends on the errors.

Different people, different standards. I might look at a child screaming for their mother because they don't know any better. But I'm not a child - different standard. Some people are terrible at math, and make lots of mistakes. I'm reasonably competent, so a higher standard applies.

No Because you cant change another person BUT you can change yourself.

Not necessarily

I don't want to overlook my errors...

if only it was so simple!!

in many ways yes its true. but i see that its saying, basically - dont be a hypocrite!

Physician, heal thyself!
