Hi Sara,
believe me you are not alone when you say you are very much wanting everything yesterday, we all at one time or another have felt like that and may continue to feel frustrated as everything appears to be on a go slow, lol. But you know something you have the potential inside of you to do a fabulous reading. It's not always those people who have been giving readings longer that relay the better messages. Complete beginners have often been amazed at their ability when they have plucked up the courage to at least try. That in itself is a brave move, one I think we should all be proud of taking.
The readathon is where you can use any tool you like, such as cards, runes, oracles, scribbles or even screwed up pieces of paper to get information from, the list is really endless Sara. Each reader here will work differently, there is no right or wrong way of working. The end result is what we are all aiming to do, and that's evidence of spirit being around us. If we can prove that they are by the messages we relay, we are more than happy to do so.
You could also try meditating beforehand, relaxing your mind and thoughts, trying to attune yourself to spirit or learn to use your intuition to psychically tune into the person who you will be reading for. When you feel ready you write down or type whatever thoughts, feelings, smells that come into your mind or atmosphere. It may sound like a load of rubbish and not make any sense to you but have faith and trust yourself. By the way most readings are given when the reader can't understand it, reason being it's not for them to understand. Eventually you will learn to recognise or distinguish what information is psychic and what is spirit.
When you receive feedback if you have been given some no's to the info, try and not let it get to you. We all can get no's in readings. In my opinion this helps keep our feet firmly on the ground for we want to always improve our method of working.
Above all Sara, don't worry about it, have fun with it. Fun makes learning so much more pleasurable, I think so anyhow. I hope this helps you in some way.
Good luck.
love Trin xxx
