If you feel like you are not prepared to do readings on people, that's fine. Except you are. But, okay. One thing you can do to alleviate that pressure of vulnerability, failure, ect. Is to set the expectation for yourself and your person: ‘I’m testing the accuracy of my abilities. I am developing my abilities. I am working on building my accuracy and confidence with this new skill.’ If you focus on future events- psychic- you will have to wait for information to be verified. If you talk with a relative or someone else in spirit with mediumship, you will be able to capture immediate feedback right away. Intuition and healing can both read energy so visualize the energy moving through this person and find where the energy is stopped, blocked or not flowing well and focus on the whys- emotions tied in with the blockages, expand that to where the emotions came from and explore using your curiosity and passing that along to the client.
