A wise man once told me that, there are two things that defines us:
"Our Patience when we have nothing and our humility when we have everything"

He told me that we are students until the day we die.

What often limits our learning is that we believe we already know, we believe that we already have knowledge, we believe that we have the answers.
You can find that this feeling of "knowing" makes us actually judge others and criticize others, and that's why wise people see that "Judging is critical but observing can be educational." Therefore we should be more focused on improving ourselves because we don't have any energy/powers to criticize anyone else.
A lot of people in the world do criticize others and make them become prisoners of their own opinions

But

I believe that we should never let complements get to our head and never let criticism get to our heart

That is why it is better to know how to learn than to know, because when we know how to learn it becomes part our mindset, it become the part of the way that we daily navigate life and that is what takes us further.

That's why Brain Herbert said:
"The capacity to learn is a gift, the ability to learn is a skill, but the willingness to learn is a choice"
