I found a video library of Byron Katie's work with students. I took some notes of main points.

Find what is kind and question what is opposing it.

When we believe our thoughts we suffer.

Identify what you are thinking,
write it on paper.
write the fears behind it below
what are you believing?
challenge your beliefs

The moment is all there is
and all there ever will be
the rest is imagination
just take care of the now

The past is kind, it's always over.

To argue with reality is to argue with God

Success is being true to who I am

Maybe I will look at the questions again, but not today because I feel unwell and it takes energy.
