Hey John, thanks for the post! It’s ok to have “those” days, don’t push it. What you have done before, you can do again; as you alluded to, you can’t have a PB everyday.
Be cool when things don’t work, just observe what is going on and put your horn away. It is those experiences that allow you to develop your awareness to get to the next level.
Be sure to maintain the work you were doing that got you to the next level; the processes are not automatic yet.
There are no extra exercises to be doing, just mind the process. Stick to the rules 🙂
Cheers,
Greg
