Take On The World Meaning

What does it mean to face the whole world? 3

What will dominate the rest of the world?

My guess is, first, there's nothing to worry about, second, the feeling that the person can react to anyone.

Which assumption is correct? Or are both acceptable? Or nothing?

I read English every day (I like it) Thanks !!

update

Each answer is so good that I can interpret it from different angles. Thank you very much!!

Attacking the world can have both positive and negative meanings.

(1) Positive, when you think you can face the whole world, it means your self esteem is high! Nothing can stop you, no obstacle can stop you ... It's basically a feeling of helplessness.

(2) The ups and downs that you can't face the whole world. You are trying to help with a problem that you can't really solve. And solve all the problems.

Help for example ...

Feel the world

Both are acceptable. Sometimes you say you love someone. Suppose you are a boy whose friends are in an area that does not like quality. You tell your friends to take over the world! In other words ... well, keep fighting.

It means working with confidence, knowing that you believe in what you are doing and that nothing or nothing can scare you.
