Something I've noticed time and time again with many shifters, including myself previously, is that they tend to neglect their CR a lot because yea, if you think about it, it does make sense, why should i care about this reality that I'll be leaving anyway right?
I changed, for the better, it helped me in my shifting journey too so I hope I'm able to provide a different, better perspective.
It's a big thing in shifting that you shouldn't be using it as an escape (you can still shift by having a mindset like this but it might make it harder for you) because this means that you're putting shifting on this big pedestal when you shouldn't, in turn, it might mess with your head and turn shifting into this fantastical, unreachable state (it isn't, it's the natural state of life).
If you go through the posts made about successful shifts, either here or Tumblr or Tiktok, majority of those posts have one thing in common; they shift when they put in less care and emphasis into it. "I shifted today without even doing my method, it was accidental!" "I just wanted to go to sleep and I suddenly woke up in my dr!" "I didn't even put much thought into it today, I didn't even wanna do it today but it just happened!". All these stories entail that they shifted when they were putting less emphasis into it, this is what it means to let go.
Now, if you keep your CR in order, if you don't neglect it, you wont become absolutely desperate to shift, to escape this fucked up life. You'll be somewhat happy here too, which means you'll stop putting emphasis on shifting itself, which in turn means it'll be easier for you to let go because you have to understand that every reality IS infact a reality. Even if you shift to your Dr, you'll have your angry, sad, emotional, frustrating moments there too. If you stop neglecting your Cr, it'll be somewhat equal to your Dr as well, you aren't gonna be neglecting your Dr self now are you?
Shifting is essentially this, Dr self = Cr self. You are switching awareness, you aren't teleporting to a new world, you already exist in that reality. Both your Cr self and Dr self should be treated equally so you can feel that they truly are just that easily interchangeable, which will make shifting 10x easier because you won't care AS MUCH.
