Everything Under the Moon

Doing tarot readings for others scares the four letter word of me for I'm afraid of inaccurate, mixed answers due to variety of spirits.
Question is how do you do it to be confident in providing accurate guidance?

#3, with utmost respect

Edit - it’s like I’ll have my people check with your people and we’ll do cake. You work with your higher self who works with the querent’s higher self. But I think I’m lousy at reading cards because maybe I over complicate it.

The only guidance comes from myself,usually,so I went with option 2.
