How do you stay dedicated to this. I know its only 8 minutes and it hard to mental enjoy this in the morning. I do it at night instead.

I think it depends on your personality, i always find myself unable to do this at night but i do it in the morning instead, however I reckon that shearing this routine with someone else is very helpful even if they are your imaginary friend you know.
I hope you find your way soon. Best regards!
