When you have two (or more) contradictory beliefs, it's as if you have two forces pulling you in opposite directions.
I have to write the best thesis, but I'm terrible at writing
I won't pass my PhD, but I can't quit
I am capable of anything, but I can't do this
These contradictory beliefs put you under immense strain. They take up so much mental energy, but it's purely destructive because the energy has nowhere to go.
What contradictory beliefs do you hold? What beliefs can you let go of?
