Self readings

Hi guys. I’m looking for some advice on doing self readings.

For some reason, my mind always seems to second guess whether what I’m interpreting is correct and if it’s my own biases coming into play when I’m trying to read into a personal situation. Eventually my thoughts get so jumbled up that I can’t focus and I end up having to step away. Obviously there are moments where I find myself being able to get through a reading, but it’s very frustrating sometimes. Are there any sort of habits I can get into to help with this?
