What is exactly impossibility?

In a dark night, when the stars are shining so brightly, when the breeze blows your hair, how do you overcome your fear?

In a luxurious room full of spaces, where you can dance anyhow you want, how do you handle your moves so that you won't fall?

When you're standing by only one leg without nothing to hold on to, how do you keep steady?

When you're drowning in a deep deep sea, how do you overcome the impossibility to breathe?

Try finding the answer, just don't get lost.
