It’s not about arrogance. It’s about countering negative beliefs about yourself by replacing them with the positive ones, because beliefs about yourself cannot remain empty or neutral.

When you understand that you can lack belief in yourself even when you know you are more than capable, you’ll understand how the reverse can be true.

You can certainly believe in yourself even when you know you are not capable enough, because establishing that belief is the only way to avoid the existence of its opposite.
