It's also really damn difficult sometimes.
I practiced for years and thought it wasn't working. And it was only at some point that I saw progress and noticed that practicing beforehand had also improved something.
But yes, it is very hard. I understand everyone who no longer has the strength to carry on. But if you still have strength, keep going! I know many people in real life who have actually made it.
One day I imagined that I would go to a really nice and competent doctor. Then I slipped into the role of the doctor and pretended to look at myself from the outside, as a patient. And then I wrote down everything that I would prescribe for this patient as a competent and holistic doctor.
All the best to you!
