If you don't want to watch the whole video, i'll summarise it below.

The first tool is meditation. You don’t lack confidence or have ‘anxiety’

You just can’t focus, simple.

Using meditation is a great tool to help increase your focus.

Second..

Knowing you’re a spiritual being and not identifying with your small self. The small self, which is the roles you have in life, your beliefs, ideas, things you like and dislike are NOT you.

You are the awareness of thoughts, feelings and bodily sensations.
