I also had a lot of time pressures, and I ended up rushing the scripting, which meant that while I wrote a lot of it myself, in the end I had to do what I really did not want to do, and in places use the words someone else's ritual. I used the least I could, but read out from one of Scott Cunningham's Yule ritual - excerpts from the Yule ritual in 'Wicca For The Solitary Practitioner' - for a few sections.
I think the most successful part was when we were free to meditate quietly on what the Solstice meant to each of us, and we all got to contribute our views. I think it being a small group helped those who are a bit more quiet and more reticent to speak up to participate. It also gave me time to stop focusing on whether I was doing a good job of leading the ritual, and connect myself. I don't know how well the ritual worked for the others who participated yet, as I haven't really done a full after-ritual debriefing, but feedback so far seems positive.
Ritual leadership is difficult, and takes works and practice, and I didn't expect a perfect ritual for my first one. I tried my best, and in future I know to be more organised and to script the ritual fully days in advance, not write a rough outline and then fill it in earlier that day, and I am considering doing things like getting a little book stand so I can both keep an eye on whatever ritual text I am working from, whether from my own Book of Shadows, my own script or from someone else's, and hold the Ritual Tools to perform actions. I am also thinking that memorising certain sections, like the circle casting chant, would be a good idea, and help keep the focus on the Divine rather than on enacting the ritual. I need to work on being confident when leading ritual, and letting things flow through me, rather than feeling like I have to be a source.
