Launch mindset drama

My last two launches made less money than my launches usually make. I’m making that mean that the launch I am doing this week is going to make less money too. I want to believe that it’s possible to do a $20,000+ launch again but my brain just can’t seem to believe that thought. No matter how much journaling/thought downloads I do I still feel like this is going to be another low revenue launch. How can I coach myself to strengthen my belief that it’s possible to create $20,000+ months again?
